- Опубликовано: 14 окт 2021
- In this video I will be casting custom fine .999 silver rounds! I designed the coins in fusion 360 and then printed them on my Elegoo Saturn resin 3d printer. I used the 3d printed models as patterns to make sand molds. The silver was melted in my homemade metal melting keg furnace. Each coin weighs between 63 and 65 grams.

Love videos like this that show “failed” attempts and how you were able to overcome them.
I live in Karachi Pakistan and I like your comment send 10 month ago
True. Really good content for ppl interested in this stuff
Your coins came out pretty good! A lot of work though.
Your failure is a great teachable moment thanks
No worries. I love watching how ANYTHING is made. The mold making process was just as fascinating as the coin casting. They're absolutely beautiful!
I love the “imperfections” in the surface of the coins it adds a bit of character to them because they are all different
The mold making process is one of the most interesting parts of the process; I'm not sure why anyone wouldn't want to see it but thank you for including it. Very interesting video.
I’ve found that casting sterling (.925 silver) is much more forgiving than casting .999 silver, even though you may think .999 is easier.
Fine silver is a hard-sell for a coin anyways, and sterling can be heat hardened.
Cast silver is dead-soft.
Very cool! Silver is really soft. I wonder if would have been easier to cast silver coin blanks and then cast your designs into iron to stamp them with?
I was wondering that myself.
this is the best way to do it I think
A good idea in theory, but iron is extraordinarily difficult to cast, and requires industrial equipment to do so
Flat coins then Lazer print

I've only cast silver once, and since it was a jewelery class, we used a sling, which uses centrifugal force to get the metal in completely.
A vacuum casting method might help you improve quality as well.
Great vid.
Where can I learn about a vacuum casting method?
I always love it when you make a new episode. It's ALWAYS so much fun to watch! I like what we learn. I had no idea that silver would be more tricky than other metals.
I love how determined you are!
I'm glad you added the mold making. I really like watching that part :)
Those silver bars look tasty.
this is amazing!! i can't wrap my head around the fact that humans have been casting coins for over thousands of years ago.
Ah, Seth, you're singing my song! Coin casting is my favorite! These turned out beautifully, warts and all.
I live in Karachi Pakistan and I like your comment if you don't mind
What a crazy yet extremely cool idea. I have been interested in trying this very thing myself. Thank you for posting the things that worked as well as the ones that didn't.
These look pretty good considering most coins are come from a mint where they are stamped rather than cast. Stamping allows for a large volume of coins to be made very quickly and with great detail, and each coin comes from the exact same thickness of metal band all stamped from the same die. It’s pretty cool to have made your own coins.
This is why stuff is stamped
Love the videos, brother! You sound a lot like Grant Thompson from King of Random!
Silver is so pretty, that’s an awesome finished product. Too bad it was so difficult to work with.
,, Osmium '' Rarest precious metal on Earth
I love melting metal, SO much, I’d absolutely do it myself if I had the resources!
Great video, thanks for sharing!
Awesome stuff!!! Thanks for showing how you made the molds at the end.
That’s why coins were struck and now stamped. You should try casting custom iron \ steel dies and strike the coins. Silver being soft you’ll be able to stamp out the custom coin while casting the dies
That’s next level! Nice job! Beautiful coins!
Make a silver cylinder -> cut the cylinder into coin blanks -> polish the blanks to a mirror finish -> make reverse and obverse dyes with designs -> press the designs into the blanks using a hydraulic press.
Very cool, This was a great one
Those looks great👍
@5:55 is why I'm here... but different stokes for different folks. 👍🍻 Great video.
They look very clean.
That brought back memories of long ago years. Eventually i learned how to press the metals. I always had problems with bubbles, even with making rings. Some of the fancier guys had a centrifuge but couldn't afford it. I did however have a press. Lot's of fun figuring it out but it worked. Just like the mint.
This surface deffects in your coins are caused by direct connection of sprue with Gates. There should be a runner between them and Gate should connect Wit runner at 90 degree angle.
You can connect sprue directly with Gates but in such setup gates should be as slim as possibile and wide- that will filter out all oxidation and provide calm flow.
And some of this deffects can be also due to lose sand in mold.
They look amazing
Very cool thanks for sharing
Wow your channel rounds looks really awesome. Thanks for sharing the entire process. Cheers 👍🏻😊
They turned out great man. Well done 👏 👍
I thought the thumbnail was clickbait they look so good
I love the mold making part.
Lol i love how you zoomed in the gob that got away.... the horror! the horror!
I enjoyed watching this
Wow, great job!!
I say vacuum casting is the only way to get great detail when casting silver. I like your wet 3D printing!
The coins you have casted now do have a look of their own though. :)
Greetings,
Jeff
Is it practical to build a vacuum caster cheap or buy one affordably?
@@brandonmccullah710 check "Craig Dabler - The DIY Castings Guy", he has a channel that does these things cheap. He has a lot of experience, and knows a lot about how to do these kind of things.
Good luck with it!
Greetings,
Jeff
He shouldn't be sand casting for great amounts of detail anyway
How about spin casting? That's what my mind immediately went to, as I've seen jewelers make very detailed items with that process.
The nasty surprise comes when you want to sell it. The original fineness stamped on the silver bars is no longer available. The pawn shop then comes and claims that the silver is inferior quality. It's all about cheating the people who own gold and silver.
They came out well!
You ought to do some .950(just to differentiate yours from standard .925 sterling) silver ring blanks(ready for stones), patterned bands or some nice pendants or something...I'd love to be able to cast my own ring and jewelry designs. Think of the different shapes you could do that NOBODY else offers!
Cure them for much longer in direct sunlight. Even in a UV chamber you generally want to cure between 8-20 mins depending on part size.
👍 I wish you success in your work!
Very nice. Loved all the work, yes, including the mold making in the end of the video. Would like to do such things over here.
Greetings from Brazil!
Man, that looks like fun🔥 ⚒️
well done, good job
Looks mint 👌🏼
Good stuff man, I'm glad to see that double side coin castings are possible :) I've been messing around with bismuth making single sided coins, but now I may have to try dual-siding it. I suppose I may have to print both sides of the coin separately and glue them together as I don't have one of those fancy resin printers. I've been following your work for a wile now and took inspiration from your foundry tong designs and reproduced them for my own little backyard forge. Keep up the good work :)
High Respect to and you're coin making.
Not a bad job. The coins turned out quite well🤠😎🤩👍
I love silvers 🥰
Those coins 🪙 very cool.
I came back for a second watch on this, Great job!
I may make some coins myself.
I think those coins came out great!👍🇬🇧
Im a jewelry caster.
Interesting to see it done in a sand mold
Pure silver is a nightmare to cast, as it cools too fast.
Also, we always keep a separate crucible for every type of alloy to avoid contamination
If you recast it and alloy it with 7.5% copper and add a pinch of borax or boric acid while molten…give it a good stir, it will cast much better. Tho now you’d have sterling silver rather pure
Nice vid. Best of luck!
This is art.
Thanks for sharing
Excellent! 👍🏻
Amazing!
Brilliant. I collect silver coins. Yours are outstanding.
This was a really good video. I've never cast anything yet but I learned a lot in this video. I'm likely only going to be melting things like brass, copper and aluminum.
👍 Danke fürs Hochladen!
👍 Thanks for uploading!
👍 Very good and beautiful, thank you!
👍 Sehr gut und schön, danke!
I like the mold making part :)
Very difficult! Good job !
Nice work
That's why most mints will stamp them. Absolutely cool video though!
Very cool! Failure to Success fine job
I would still buy one of those man.
👍 great video thanks
Respect for leaving a comment to the author. I would be grateful if you look at my content and rate it. In one of the videos, I make golden matches with diamonds out of ordinary matches.
lol the mold making is the best part!
What you should try it heating up silver and hammer flat and round. Stamp on the designs using steel stamps. Or make the coins out off silver clay. And stamp on your designs. Then blast the clay so it will turn to silver
Cool thanks
Have you tried an alchol+graphic spray to improve the surface. You spray is on your mold and either let the alchol evaporate or touch it off with fire. Leaves a hard graphite coating. Also, you should print your gating and you would get a better result.
You should make some Garden of Eden coins with Adam and Eve on one side and a snake in a tree on the other side.
When casting dental alloys we preheat the casting mold medium so it is a similar temp to the alloy. This cuts down on turbulence a great deal. Anyway you could preheat the sand?
Yes. Silver is hard to cast. Need extremely hot metal for easy flow and extremely smooth...but quick...pours.
I tried and gave up on casting my coins.
Electing instead, to melt and roll sheets that I can cut the coin blanks and stamp tbe designs using a press.
My dies are being made as I type.
Wish me luck.
Sounds like fun!
Idea: cast a metal mirror, then polish them, and then compare to modern mirror.
Excellent idea.
Well, now we see for ourselves why silver coins were more often stamped than molded.
Enjoyable video, thanks for including the mistakes!
Hey man I'm getting into casting things but I'm having trouble with the ceramic coating. Not the sand. Can you let me know what you use?
Son l think you did a fantastic job
are we gonna talk about the shape the molten metal makes at 2:27??? 😳
A centrifugal casting machine is what is used for casting precious metals
Release a short ringing the coins together. Silver makes a very pretty sound when rung.
Me : how much have you the fine silver?
Robinson Foundry : YES
I think you showed why coins are struck in a die instead of cast. Looks like a lot of fun.
you could try lost wax/pla casting since the plaster mold should have a better finish
Hey, cool video and very nice to see the different processes, including the defective pours. I'm trying to cast some bronze coins about 30 mm to 3 mm thick and we're having trouble with coins not pouring all the way down the cavities. What do you think could be the problem ? Thanks again for the video !
Nicely done! I have found that when making coins, sterling silver casts much better than pure silver.
I live in Karachi Pakistan and I like your comment
Nice !!! Brazilians like.
Skulls are cool
Try a longer sprue,put a can with greensand over the in spout and pour through that, you should be able to pour more coins at once
Don't give up on silver casting! The coins ended up beautiful, but I wonder why you used sand casting instead of using plaster. I used to make jewelry way back in the stone age when I went to college, and the refractory plaster we used would very accurately capture the surface finish of the wax model. I've also spent some time in the more recent past experimenting with 3D printing and have always wanted to use it in lost-wax casting. I hope to see you continue to experiment with silver!
cool
hola me gustó el video saludo:
🤜🤛👍 👏👊
Id love to hire you to make some custom 1oz silver coins for Christmas 🎄 stocking stuffers, maybe even some dime size out of gold!
I really enjoyed this one. I think you might have some really cool coins using a technique where you cast blanks and then use a stamp or press (like the ancients did) to imprint your design. It might take some practice to perfect the technique, but you could try using pewter blanks to conserve on cost.
I’m a new stacker of silver and your videos are absolutely amazing. Thank you for the videos. Do you sell any of the 2 ounce rounds from this video? I’d love to have a coin like that for my collection
I wonder if you could cast in a vacuum chamber to avoid bubbles.
Obviously good cast design is an alternative solution xD.
