Thank you Dan. I couldn't agree more. I can't stand when ppl say " never clean your coins" and just leave It at that. I believe in proper restoration of coins with out jeopardizing the orginal integrity of the coin.
Daniel, I learned a lot on watching your video, thanks
Now I have a question. I found 2000 D Massachusette US quarter in a silver planchet. Silver planchet supposed to be on San Francisco mint only. Is this rare?
Helo mr Dan may you let me know how worth between prove set coins & coletor coins set?
id like to know if you buy coins your self to add to any collection
hi sir, can i ask, if i use water and a common household bar of soap, and wash the coin with my bare hands and soap for about 30 seconds, then rinse and pat dry with a towel, would this remove the patina or damage the coin??
This is the rule of thumb I use.. if it only sells for its weight in metal, do as you wish.. if it has more value than its weight in metal, then don’t clean it.
Darth Silver, agreed.. Good rule..
What should you do if you want to sell it list it but it has green stuff on it?
@@milwaukeeontuesday2347 like toning? Do not clean it if it is toned. It’s already more valuable
Thanks.
So can you clean copper coins with cheese cloth? JUST TO SEE IF ITS DOUBLED.
Thank you Daniel for clearing this up. It's best not to clean the coins in the first place, especially if you don't know what you are doing!
Great video! Thank you! As a new collector, you are the only one who broke this down! Following you for sure!
Thank you so much. As a novice coin collector it's very nice having community that is so generous imparting their knowledge to the rest of us.....great videos.
I'm probably older than many of the coins in most people's collections. This being said, I have been advised by the so called experts, of my generation to never, never attempt to clean any coin no matter what the condition of the coin. I had acquired a somewhat extensive collection of coins over the years. Unfortunately, I gave up on collecting coins when it became too expensive to acquire some of the coins needed to complete my collection. Coin collecting was a fun and fascinating hobby enjoyed 😉 by many, usually started when young. Most of the coins could still be obtained from the change received in day to day transactions. As a young boy my grandfather often gave my sister, and my brothers and me pocket change whenever we visited. The coins he gave us included Indian head pennies, Buffalo nickles and Mercury dimes and occasionally even standing quarters and even walking half dollars. I would eagerly sort through the coins to add to my collection. I also traded coins with one of my best friends. However, when I eventually had to resort to purchasing coins, as the hobby grew and the ranks of collectors swelled, I gave up and sold my collection. Coin collecting was no longer enjoyable for me. Now I am only interested in purchasing certain key coins to be given as gifts 🎁 to my sons and daughters and my grandchildren and great-grandchildren. So cleaning some coins are worth the effort in order to return the coins to a legible condition in order to make out the dares.
@@stephenhendershot6180 Thank you for the story, Sir. It encourages me to keep collecting my coins!
What kind of coins do you have
@@coleburnett2803 .... everything ... in quantity .. inherited most of it...will take me years to go through it all....
Great information as usual. The clarity around preserving the striking layer is the key and you drove that home. Thanks!
Daniel, my name is Steve I just got through watching your video on cleaning coins. I'm a somewhat of a coin freak. I also metal detect I don't even clean the coins I find. I've seen some very nice coins cleaned before and I knew that they had ruined a prize they thought they had. It's a waste to watch some people try to fool not only themselves but others. I enjoy your videos. I can tell a professional at what he does, and I can tell you have put the hours in your passion. Thanks for your time. Respectfully Steve
I have been thinking about this for a while! Thanks for clearing this up. It makes sense to clean off the dirt without harming the strike layer, but if it is damaged, that’s what we don’t want. It never made sense to me to leave a bunch of dirt on a coin to where you couldn’t really see the details! Why would that be wrong to clean? I want to see my coin!!! Lol. I got some really slick shield nickels and completely doused them in Nickadate until some great details came out. I wouldn’t sell them as they are clearly damaged, but they’re mine and I like the details in them. They look cool to me! Again, thanks for clearing up a weird area in coin collecting for me.
Always a pleasure watching your channel! I've learned so much from you since you started!
Thank you, so glad to know that!
Thanks Daniel, everything you spoke of makes perfect sense. I've been dealing with this issue for sometime now; however, I don't trust just anyone's answer to this delicate question. You I trust your judgment, you are a bright man and I sincerely thank you for your point of view.
Blessings,
Louis
Dude! I am glad that you addressed the copper issue at the end of the video 👍 I didn’t know that acetone will turn copper pink 👍
One thing to bare in mind when considering the cleaning of a coin is the reactivity of the metal that it’s made of. What if the coin has something on it that has protected it for fifty years and you remove it ?
Well, you may get bright spots where the gunk was.
THINK BEFORE YOU CLEAN 👍
EXCELLENT advice
100% acetone won't react with metallic compounds. It is an organic solvent. That's simple chemistry. However, acetone that isn't 100% pure may well have numerous other additives that are reactive.
Hey Daniel I just want to thank you for keeping a great attitude and reputation while maintaining the great standards of cion dealers. You are a phenominal teachers with an excellent standard of honesty. You have showed me a great deal of key factors in collecting and maitaining my coins. For tbis Id like to show some of my grattitude by asking you to help me sell my 1943 copper cent. I am a 57 year old teenager that has sustained a traumattic brain injury . Now this was due to a car accident that happenedde o back in 1987. I was left in a coma for 3 weeks and one day (22 days) . When I awoke I was paralized on the right side of my body. And have been recooperating since. This recooperation process has been so difficult in that my brain is so slow at processing my thoughts that in turn makes everything I do ten times harder for me to accoplish
You can send me images on a set of scales unless it is already graded to portsmouthcoinshop@gmail.com
I have learned so much from watching your videos in last couple of weeks! Thank you for always being so detailed.
Thank you so much! I'm about a week into coins. Mostly pennies. Have watched enumerous videos from countless sites. Had a lot of questions. I have learned so so much from you that I just don't click on anybody else's anymore. Just wanted to tell you that. Thanks, Daniel!
Thank you for the excellent advice. Stumbled across a video on coin collecting, watched a few more, then started looking at the coins in my old coffee can, aka piggy bank. Found 3 DDO quarters in the first half hour. Very exciting and I'm hooked. One was pretty dirty so I just used enough water to see it better. So much talk about color and patina. Want to have them professionally graded but didn't know if I should send as is or not.
Watch my video on what to do ruclips.net/video/uPAvUteGu0Y/видео.html
I just found your video and subscribed. I'm glad you explained that, I'm fairly new to buying Silver and Silver and Gold vintage coins. I have a couple that are just filthy but when you look up close, there not scratched up at all it's almost like someone had a fairly new coin and dropped it in the dirt and it layed there for 40 or 50 years. So I've been trying to find a way to just get the dirt off without damaging it. Everywhere I've looked it says "DON'T EVER CLEAN YOUR COINS!" But like you said, someone is cleaning them and it's ok.. Thanks!
Best coin vidioes on you tube done by this guy! Keep em coming brother!
Thank you for your always informative videos. As a relatively new collector I often use your videos as a reference as which coins are valuable which web sites I can use to verify my suspected valuable coins and any coin questions I may have . I find your video as wealth of information with out all the carnival antics . Just strait up with minimum theatrics . I thank you for information.
I've just began collecting, my dad left me his coin collection and I've become interested. I appreciate these vids, and have subbed for more. I also was wondering where I might find forums of collectors who can look at my coins and give me a better understanding of what is valuable and what isn't
Here's our community coinauctionshelp.com/forum/index.php Always check my other videos I have several that will help you.
I'm a new coin hunter/collector and have to say this was quite informative, 3 years after originally posted. Thank you.
I'm new to this area. However watching, and listening to your videos is amazing to hear about what to look for in coins as far as colors and errors. Also, I'm glad to hear about " How to clean up your coins" I'm guilty of using toothpaste baking soda, and vinegar( not all at once) I did it different times. It didn't come out clean!!
Thanks Daniel!

I have old copper coins that are covered in sticky stuff and some have green corrosion. Is there any way to clean them?
Man, I used MS70 on an 1848 Prussian piece, it was so tarnished that it was hardly recognizable, I really hope I made the right move... The reverse looks fine, however, the obverse is the part that you can tell was modified. Either way, it was nice to know that the MS70 doesn't do any major damage, thanks for all the information given!
If you’re not selling it, and enjoy the coin more now, you made the right move.
This is one of the best informative youtube vides ever. You're very knowledgeable and extremely well spoken. thx man.
Thank you
Thanks for the info. Somebody said to use olive oil. But that person was adamant about NOT cleaning any coin. I have tried to remove some crud from coins with soap and water and a q tip myself. But I was under the impression that you don't even touch the coins with your fingers. Thank you for your knowledge and showing it on RUclips.
You are much more relaxed now a days. Still a good and valuable video. Thanks!
Hi Daniel. I am learning quite a bit from your you tube pages.
Recently I have been told by my doc to learn and do something that will keep me busy and I would get great enjoyment out of it. So, getting into coin collection seemed like a place to start. Today so far I am having great success. I am mainly collecting pennies and nickels.
How did you start? Where do you get your coins from? The Bank?
I happened to get a 2yr old Red Book of US coins. It was a great find. I liked the articles and info as a newbe..................lol
Thanks for sharing info.
Vickie C.
I would like to add that the decision to get your coin cleaned might also depend on what your piece is. If you want to clean some common date sliver dimes you find metal detecting, I say who gives a damn. Clean them using swamp water.
Very interesting video. Thank you for educating novice collectors around cleaning/not cleaning coins. Keep them coming
Daniel, thank you. Watched the whole video, VERY informative. Thanks again. I've been watching ALL your vudeos.
Thank you
Well the copper coins I've dug up w/ a detector are so black & narly that I can't read the date & mint w/o light & magnifier. So although I've put off cleaning them due to Taboo , I've finally decided to clean them. I'll use vinegar & salt first. Depending how that turns out will decide what I do from there. I figure that , in their current condition , they are pretty worthless. I won't try to achieve an MS state but darn it, I want my G'Daughtet to be able to appreciate the completed wheat penny collection. I just don't see any logical alternative. She will love the collection even if it loses value I'm sure. It's alot better than the black overall look when you can't even read the date & mint
O boy you awnser all my questions I ever had in the video. You have proven again you are the go to guy and channel for any thing to do with coins.
Great video! I like your presentation and narration style. Easy to follow and understand.
Great video, thanks. One question, can I use a wooden toothpick to see mint marks and lettering better when they are obstructed?
Yes you can
What are your thoughts on using a dry Jewlery Cleaning and Polishing cloth? Not using any other rubbing or polishing compounds.
White Vinegar and origional Tobasco Sauce...are they too abrasive? What are your thoughts of using a Jewlery Dip cleanser?
If a coin goes through the wash by accident is that considered damaged? And if a coin was "washed" using baby shampoo and water, then patted dry, does this damage a coin? Thank you. I love your videos. I am learning a lot!
If the coin is circulated it will harm it and even if it's not it can.
I am a metal detector guy and when coins come out of the ground you can't even read a date,
I found Mothers Mag Wheel polish and a tooth brush you can bring them back from the grave.
Coins that come out of the ground are in most cases considered environmentally damaged. I myself metal detect.
Thank u! Yr advice is always so helpful & is very appropriated.
Thanks for the information. Tape can be a problem. I tried Bestine for some coins that had wax. Yes wax. Actually worked OK.
Bestine is something I used when I worked at a magazine and (I am dating myself) we did paste up boards with wax. Sadly, the older
stock books for coins used acidic paper stock, which is what causes toning. I would tell anyone who is a serious collector to check
to make sure they are using acid-free envelopes or other paper items.
I have a silver coin that had a rubber band melt on it and left a black mark. I think it's about an AU58 if not an MS. What do you think would get the black mark off without disturbing the rest of the coin? I was thinking about sending it to PCGS, but wonder what they might do.
I don't know. Never could remove them
As a metal detectorist I now leave my old copper coins alone. Not soon enough though found out trying to clean a1822 Large Cent I lost some detail on it. Thanks very informative 👍
What are your thoughts on using the baking soda method? Sitting coins on aluminum foil in basically warm water. Junk silver only and already damaged cull common date peace dollars. Some coins I have were previously buried by the prior owner and are otherwise filthy haha. Thanks!
I don't use it
Thank you SOOOO much for giving us this info 😉 very helpful!! To know. When in doubt just leave it alone 👍
That was good educational advise if we want our coins to profit.
I get what you say. I have some better coins with splotchy dark toning. Can acetone remove that? Or eZest or MS70?
Under normal circumstances, no. If the coin isn't a high numismatic value coin and (or) crud needs to be removed, I personally feel it can be cleaned. Any of my lesser value coins in my albums, I've no problem with gentle cleaning. Higher grades and those I'd like to have slabbed, I wouldn't. Type 1 is as far as I'd go.
Thank you Daniel for you video... I enjoyed it... very informative!!!
Daniel Thanks for sharing this Information, I myself have never cleaned a coin, just incase to be safe...
I have a 1922-D Peace Dollar in pretty decent condition (releif wise), but the obverse seems to have had celophane tape across her face leaving it a shiny silver while the rest of the coin has taken on a black toning on the entire coin with some red-ish maroon toning on the reverse.
My question is: What would be the best solution to restore it?
You can't but no one can really answer your unless it is examined in hand by a knowledgeable and experienced coin restorer.
I just started following your web page. Very nice information. I have a question. When "cleaning" a coin. Do you use Acetone?.I have used it with a Q-Tip that is rolled across an area that is infected with PVC. And only a coin that is not going to be graded. Have you had any issues with this style of cleaning ?
No I don't use acetone but many people do. I use ezest to remove PVC or glue and tape.
Thank you, good advise. I have a 1904 silver Dollar. It’s in pretty good condition as far as the fine lines, etc. the problem is, the coin is very dark. It looks dirty. Do you think I should try clean it with toothpaste to help the value of it, or would you just leave it alone.
I don't give advise like this.
THANK YOU DANIELE, GREAT VIDEO TO THE END!!!!!
Hello. Thanks a lot for the video! I have a question.
I have had a bag of really old coins that ive been storing for years. Some of them were inside another bag that belonged to my grandfather. Early 1900s coins. But they were all together in a messy bag, and were used in its time. They all have these little chips and scratches. Are they worthless now? Should i just clean them at least for the coin album?
You need to take them to a dealer to look at in hand.
@@CoinHELPu thank you !
thank you, you really care when you teach people . and that matters alot. LonnieRay. p.s. i won't clean anything with out a ok from a pro.
Is dipping a silver coin in baking soda solution consider type 1 or type 2? No rubbing involved, just dipping and rinsing.
Hey sir. I hope this isn’t a dumb question. So if you just use soap, water and a very soft tooth brush to get dirt off or just water is that ok?
i am sorry but I don't recommend cleaning methods on coins, it's a case by case issue.
Question. If you get a bank roll of coins, say nickels, and you how people put the nastiest things in their pockets. Gum, candy, other. It melts or somehow adheres to the pocket change. So then they peal off said coin to to pay for something and it ends up in that roll. Is it safe to take warm water and a soft cloth to just wash off the gunk?
Yes, pocket change is safe to clean.
Daniel, just wanted to let you know that I have a lot of respect for what you are trying to share with our community.
God bless you my brother in Christ Jesus 🙏
Thank you
Damn...to think my mum found loads of coins from the 1800s and she uses em as curtain weights xD I had no idea coin collecting went this deep, really interesting, it'd be nice to clean a couple of em up too just to see how they come up, she's got a box of em
Can you use a silver Jewelry cloth cleaner?
I have a 1877 cc dime that would be xf - au but it has black gunk all over it. What should I do? It's definitely xf quality.
Thanks for the advice, if a person chose acetone only would adding it to a micro vibration device (like a jewelry cleaner) help the acetone be more affective? I have seen some suggestions of acetone and cotton ball. Understanding your disclaimer of responsibility what are your thoughts? Thanks in advance!
I figured acetone would damage the coin. Or is it just safe for a short soak or dip?
I will have to try the ezest, I dip one in acetone and rinsed in water, and it looked normal, then a quick dip in Ms70 ,seems like the ms70 is slippery when you rinse it, because I've noticed that you have to rinse it until it's not slippery any longer. BUT, it seems to make coins brighter which in my view looks cleaned. I only try on AU, type coins that can't loose, I am determined to learn how to properly restore a coin as well as the professional graders can.Thanks for the informative video's. The old guy in Florida 😎
We love old guys
Obviously a young man you are,❤
Will a dirty coin be bought as high a clean coin. Thanks.
If it is a key date - I leave it alone. If it’s circulated Constitutional it is almost always scratched up a bit already. If it is a gem coin pulled out of circulation, it’s usually already pretty clean.
My experience is if you had two identical Mercury dimes, say both were equally damaged, but one had been shined/cleaned with the baking soda and foil method, the cleaner coin looks better and will sell for more.
If the internet tells me my coin is worth $4.50, I’m probably going to try and get $9.00 out of it, and being clean helps that.
I’ve got a very old, beautiful Morgan that is in incredible physical shape, but it is tarnished damn near black. I will never even think of cleaning it.
I have copper pennies that have changed color in spots to green. It's difficult to see details to evaluate. Any suggestions? I'm a newbie collector of 4 weeks!
Thanks!
I have only used dawn to clean some benjamins and it worked awesome taking off a sticky substance. When i worked at a coin shop every Saturday a dipped a few silver rounds to keep them clean .never did we ever clean a coin.
Hi Daniel...Thank you for all the great information.
Thank you
I'm from Melbourne, Australia. As we are in a lockdown of sorts, I've been trying to catch up on my coin collection. I went to the bank and got bags of coins, mostly circulated. When sorting, my hands got so dirty from the coins, they are filthy. Because of Covid, no one is really using coins anymore so the bank is the only place to get them. Many do have gunk and dirt. What would be the harm of either soaking them in warm water or water with a little liquid detergent and using a cotton bud in places? I do have some coins I definitely won't touch but for the circulated ones I am putting them in coin albums so want them to look decent.
The q-tip will still leave scratches.
Soak in vinegar for half hour then use a pencil eraser lightly to bring out the shine. Iv done this to old English copper coins that were unrecognizable and they come up like brand new. Just don't leave in the vinegar for too long.
I have found an 1866 5 cent piece i don't know if to clean or how also a lot of Morgan silver dollars going back to 1880 also a lot of 1921s an 22s and other dates..what do I do? The have been stored for a very long time given to me by grandmother. How can the "safely be restored or can they?
You would need to call NCG or PCGS about restoration. The coin might not need restored.
If you just wash the coin coins by just soaking it to a certain liquid to clean…without brushing it…is it no good too?
I learn so much from your informational vids, thx D👍
This topic of cleaning coins is a good one. Define cleaning. Restoration, by the grading companies is actually cleaning the coin. They can do it and it's ok..But if you do it, it's cleaned. Do they also use EZest, or MS70?.I have used ms70, and it works well. Good video 👍
I don't know that answer
Thanks for Sharing my friend
Thanks. I had a disaster. I released the video last night and realized this morning the soundtrack was off. I had to re-upload.
Daniel I have a 1943 p copper cent that is very slightly getting some green on it. I am going to take it to PCGS on the 11th of Dec. And I believe that it will be resored professionally so Im not touching it as I put it into a mylar flip. Do you think that it will be alright? And thank you for pinning some of your videos up for me. I am going to find your facebook account and leave you some recent pics of this coin asking for your honest opinion . Thanks again for the help that you give to us ignorant folks . Thanks to you I am overcomming my ignorance.
Sorry if this is a stupid question, i understand you dont clean copper coins, but what are your thoughts on wiping pennies found in pocket change "circulation" gently with a baby wipe
Can't hurt common coins
@@CoinHELPu guess what im confused about is, if I decided to get a circulated penny graded, will they be able to tell I used a wipe on it and not give the higher grade because of the wipe being used, i hate to spend money to have one graded and get it back as genuine tag instead of the regular grade.
Awesome directions and thank you!!!
Thank you for sharing, awesome information I just subscribed!
Thanks for the sub!
I probably wouldn't touch coins as I know messing with them does affect the value... I'm hamhanded with that kind of stuff, sure to leave scratches and stuff.
However the question I'd have is on brass tokens. I have some from an old arcade... Is cleaning brass tokens as damaging as cleaning nickel/copper currency? I'm not sure if brass has a better surface that allows for some kind of chemical cleaning. They are very sturdy though. I might just leave them... but I really would love to see what a few of these look like cleaned up like they were newer.
I am new to coin collection, I when I say new I mean 2 weeks. I’ve invested in a microscope and been going through my piggy bank. I have question when should we send it to get graded ? I found an off center 1972 quarter and a nice 1979 but I don’t if it’s worth sending out. Any advice will help
You can watch this video, questions like this can't be answers in the messages. ruclips.net/video/6OdHAUR9Z-E/видео.html
What If its just common constitutional silver? Is that okay to clean? What's the best way to clean them?
How do the restoration places clean coins? I have an old peace dollar that has old gunk on it that I’d like to remove. Not like just age but maybe glue it something that was sticky almost 100 years ago.
No one knows but them
Hello Daniel. When I clean my coins I just wipe my clean as I can with a paper towel and leave it alone. Thank You.
I made a mistake and cleaned several of my coins matter of fact a pretty large quantity how much do this lower the actually value on the corn itself?
Is hot water and a soft dry cloth ok on copper coins?
This was a great video. Thank you so much! ☕👏🏼✨❤️🔥😁
My problem is that I have super rusty and oxidised coins, so the image is no longer visible at all, and I fear it will just get ruined, but I haven't found a proper way to strip away that much rust. They're also really old coins. Can you help?

Is this EZest only good on silver? Just looking for your opinion.Thank you.
Always great info. I will only practice on junk silver gor to get some experience some how.
sometimes I clean my silver dollars with virgin olive iol- it should be in a glass container like a small bowl. it works best with coins that have dirt and crud on them.i soak it for a few months, changing the olive oil when it starts to change color- the idrt just soaks and falls off- I then rinse it in warm water, make a mild solution od dawn dishsoam and warm water,swish, not rub it around to get the oil off, then rinse it again in warm water and put it on a soft cleaning cloth,lightly pat it dry,rol the rim on the towel so the reeds dry, then leave it out for an hour to dry. I wear gloves- it just upgrades the coin.
Does this clean off pvc gunk?

I use a sandblaster, clean as a whistle. Lol ...kidding. thanks for the video Dan.
Excellent video! Thanks fam 🙏
Great photo examples!
Hi. I just inherited some coins and paper money that had been stored in a safe. It all smells bad to me. I’m clueless as to what to do. When I use the term “clean” I was thinking mild soap and water with a super soft sponge just to maybe get the stink off. I don’t think that’s what you are discussing here. I know some of these have a bit of value but I don’t even know where to start to find out which are. Any suggestions or pointers are welcome. Thank you.
No, don't know what to tell you about paper money like that, it could damage it. i would call NCG and ask about their conservation services and if they do currency.
Thanks for telling me! Im really new to coin collecting so luckily the only 2 coins that i think are rare are a South african 2002 world cup 50c and a South african 1c coin
Hi i have a few old rear coins and i don't know how to get them authenticated or "restored" if needed to sell them. Any advice would help ty
You call PCGS or NGC for that
Hi Daniel. Could use Blue Ribbon which is very very expensive or I saw a man use something that a dentist discovered called Conserve Safe Coin Solvant. Which doesnt ruin the lustre or destroy the integrity of the coin in anyway. But remove PVC marks grime dirt oils. And has his coins come back from the graders with top grades. I wish there was a solution for carbon spots on my 1954 New Zealand Pennies. Nice coins ruined.
We use ezest it has stood the test of time for coin dealers.
I acquired a rare coin, a copper-nickel coin, with green molds, I thought it is uncleaned, but as I watch it closely, it has hairlines evidence of rough cleaning, my conclusion was it is cleaned even before green molds takes place, so I just clean it. then to my surprise, there are lots of rust dots sticking in it.
If I didn't cleaned it, I think the corrosion will take over the whole coin, so I guess I save it from further damages..
I don't have intention of selling it.
Just for my personal collection.
There are still few rust dots in it, I hope someone or anyone can suggest how can I safely remove those rust. tia
The only coins I hardcore clean are my cheap coins with historical value to me but are otherwise worthless,like my Soviet coins
Suggestions on "cleaning" coins found out of the ground? I have a metal detector and... well, you know, sometimes you get lucky!
Soap and water. I just don't cleaned coins like that myself.
My ancient Greek coins have been cleans with olive oil. They look less pitted and have a nicer color and feel.
Another very nice video. Thanks for the information.
