Copper is one of the most reactive metals used to make coins. Because of this, copper coins need constant care to maintain their original beautiful appearance.
In this insightful CoinWeek video, Early American Coppers president Bill Eckberg demonstrates the proper preservation techniques for copper coins and describes the simple tools you will need to do this yourself.
If you like Bill's demonstration, please consider joining EAC. Not only will you gain access to some of the most knowledgable collectors in the field, but you will also receive EAC's excellent periodical Penny Wise.

This hobby the gym and my dog are all I have
We use “Coin Care” at our store with a Q-Tip and that usually does the trick.. good solvent that doesn’t disturb the original surface of the coin but removes any dirt or grime that gets on these coins.
Thank you. Very short and informative.
It seems like blue ribbon and 1,1,1 trichloroethane are not sold anymore? I can’t find the “care” product either. What should I use now?
What about "gunk" stuck to coppers? I heard that soaking in acetone is acceptable.
can this method be used for other coin types such as brass, bronze, silver etc? Also, can this be done to let's say a new (2016) lincoln cent before being stored?
Does this method also work on silver? I'm looking for something to help preserve new silver bullion rounds to help prevent milk spotting. Thanks
So, PCGS won't slap my coins with a "details" grade if I use this (or rather the non-carcinogenic replacement)?
What kind of oil in Blue Ribbon? What do you do if a copper coin has green on it?
New Lincold cents and old copper were never the same.Different composition all together.
Good video for a beginner.well explained
Where am I able to purchase the paper envelope and cotton liner (as well as the solution)?
I'm thinking Wizard Coin Supply will be able to hook you up. If that doesn't work, reach out to a dealer that sells early coppers.
At 4:00 that was PVC damage
How frequently should I apply the product?
I thought that mylar coin flips were inert? They contain no PVC or oil. So are you saying that they are not safe for long term storage for copper coins? What about silver coins?
Are NGC/PCGS slabs airtight? Would they prevent further corrosion if they're airtight?
ngc and pcgs slabs are airtight.
@@humongousd no they're not, coins can change significantly in a holder.
Or instead of all this can't we just place them in air tite capsules or NGC/PCGS slabs to prevent air and dust from touching the coin?
If coins go into NGC/PCGS holders with problems, the problems will only get worse. Also, coin capsules are not inert or airtight. Additionally, a majority of the most advanced copper collectors crack their coins out of holders and store them in the manner Bill demonstrates in the video. EAC also grades copper coins differently.
This is for copper. Copper is really reactive to environment. I worked I. A restaurant with a lot of brass, 2x a week I had to polish all the brass with brasso or it would quickly get hazy or green spots or white spots or black or brown spots.
Brasso is not recommended for coins because it is an abrasive of course but the point is even in capsules or slabs, which no matter what they say they are not completely air tight, the copper will tarnish which is corrosion.
By doing what he's doing he's conserving and not cleaning. He's putting a light layer of that product on top of the coin and refreshing it from time to time while removing whatever might have gotten on top of the product treatment since the last time it was done.
This inhibits the tarnishing to not continue further into actual corrosion. It stops it from getting g worse and preserves the surface of the coin with that layer of that product in its current state.
I am interested in finding out what happens if this is done to a brand new red cent? If it will maintain that red color or if it still fades to red brown...
@@sparkyjones560 I think the fellow said that after a thousand years copper will corrode, but what he does he said will make them last a few hundred years.
I found an imperial George large cent. It was/is incredibly encrusted in sand/silica, etc. I am unable to see the date, or the reverse. I made out the face, and saw a mustache before I knew what these imperial George pennies and half pennies. I did work on it a little bit, trying to be careful enough to clean it up enough to see a date. I thought if I could make out a date, it might be worth sending in to get professionally done. It has a green tarnish on it, and I'm trying to maintain the tarnish and not get down to bare metal. I could use some advice/assistance. You never know, it could be a 1933. There's 1 that is floating around out there. Besides that 1 floating around, there's only 4 in existence and one of them sold at auction for A LOT of money. The odds are it isn't what I'm hoping, but I do want to be careful. Thanks in advance for your reply
Good luck getting a reply here. I had a similar question and another person said these products are no longer being sold.
Crc gun care.. Just about all that I need,.. Great preserving oil..
do you need to dry coin after
Oil doesn't dry. Just don't put too much on, or you plastic sleeve or paper folder will be greasy...
111 TCA is super expensive, like $30 per fl oz.
Thanks for the information regarding this coins l have allot of copper penny from Indian head until today However missing 1877 very hard to get -just like 1895 Morgan silver Dollar The new cents don't look like the are really good to collect them -after 2-3 years (sorry l have to say that)this coins looking like scrambled scraped metal nothing else not even close to 1859 -1909 lndian head penny's or Lincoln cents 1909-1982 Good old days when American coins was made from gold silver and copper lts very nice to look at really money -NO plastic or paper need it or Federal reserve crooks after 1913 No-one know exactly how many silver Morgan's Dollar's was melted and shipped to England no need for distraction GREED and stupidity always been bad combination Good bless You all
What is your point, and what does that have to do with this video?
Doesn't this count as cleaning, which would result in a details grade and therefore reduce the value of the coin?
No. The solution being used is a protectant. And as Bill suggests, this is done by virtually every connoisseur collector of large cents and half cents. We produced this video to demystify the process for collectors.
Coins become toned, oxidized when exposed to air. This toning layer on the coin is called patina. Cleaning with chemicals strips the patina from the coin. But when you use oil such as was shown in the video, it prevents air or moisture from coming into contact with the coin. The oil doesn't strip the surface layer of the coin, it protects it...
No this counts as preservation or conservation, not cleaning. Generally abrasive or corrosive work on coins is "cleaning" while gentle cleaning treatments or conservation treatments are "preserving" or conservation".
They say it's bad to clean coins. What is really meant is its bad to use abrasives or acids or polishing for instance.
Copper cents wouldn't last without it being done. It tarnishes too quickly and just gets worse from there.
I wonder how the coin graders feel about that.
the graders do it themselves during the conservation service
Wow, using that on an early Lincoln red cent is a scary thought.
I use a brush like that to brush my teeth.
HEY ! I WAS GONNA SAY THAT.
Awful big mouth.
What's wrong with WD-40 or gun oil? Sometimes I wonder about these grading companies!? What? They can restore a coin but you can't? Sounds to me like it's just a way to make more money off coin holders.
Ocd there
This is garbage. You wouldn't get me doing this! I'd rather chance the corrosion and toning over any brushing of the surfaces, no matter how lightly it is done. Heck, I've gotten coins returned to me Details graded as "Wiped" and I couldn't even notice the area of the coin that was wiped.
