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’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.

I love the “imperfections” in the surface of the coins it adds a bit of character to them because they are all different

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?

A good idea in theory, but iron is extraordinarily difficult to cast, and requires industrial equipment to do so

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 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.

Silver is so pretty, that’s an awesome finished product. Too bad it was so difficult to work with.

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'm glad you added the mold making. I really like watching that part :)

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.

Awesome stuff!!! Thanks for showing how you made the molds at the end.

I love the mold making part.

Ah, Seth, you're singing my song! Coin casting is my favorite! These turned out beautifully, warts and all.

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

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.

That’s next level! Nice job! Beautiful coins!

They came out well!

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.

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.

They look very clean.

Very cool thanks for sharing

Wow your channel rounds looks really awesome. Thanks for sharing the entire process. Cheers 👍🏻😊

I love melting metal, SO much, I’d absolutely do it myself if I had the resources!

@5:55 is why I'm here... but different stokes for different folks. 👍🍻 Great video.

Very cool, This was a great one

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!

High Respect to and you're coin making.

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.

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!

They turned out great man. Well done 👏 👍

Those looks great👍

Those coins 🪙 very cool.

Wow, great job!!

Thanks for sharing

Love the videos, brother! You sound a lot like Grant Thompson from King of Random!

well done, good job

Man, that looks like fun🔥 ⚒️

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 :)

I think those coins came out great!👍🇬🇧

I like the mold making part :)

👍 I wish you success in your work!

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!

I enjoyed watching this

Very difficult! Good job !

Brilliant. I collect silver coins. Yours are outstanding.

Excellent! 👍🏻

Nice work

I came back for a second watch on this, Great job! I may make some coins myself.

Not a bad job. The coins turned out quite well🤠😎🤩👍

this is amazing!! i can't wrap my head around the fact that humans have been casting coins for over thousands of years ago.

Amazing!

Lol i love how you zoomed in the gob that got away.... the horror! the horror!

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.

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’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 love silvers 🥰

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.

This is art.

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 !

This is why stuff is stamped

I would still buy one of those man.

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?

Release a short ringing the coins together. Silver makes a very pretty sound when rung.

I wonder how they would come out cast in bronze? Have you tried baking your molds to get them has hot as possible before trying to pour your metal into them? You may bet a better flow.

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?

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!

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.

That's why most mints will stamp them. Absolutely cool video though!

Son l think you did a fantastic job

Thank you for that! New to your channel. Would investment casting have helped you? Either the gypsum based or ceramic shell? I'm keen to see details reproduced. I would think any internal angles pose a challenge for sand. That is Delft? Have you ever used Mansbond? I just heard of it. Thank you! I have been enjoying your videos and already subscribed!

Great video. Have you considered centrifugal casting for coin production?. Often used as a way to produce fine detail things like warhammer models back in the day. Also i think it will mean less work after the cast. I think you can use plaster to pour the casts too. Some jewelers 3d print using a wax like filament that totally disappears when molten metal is poured over it, no need for a 2 part cast.

You rock! I need to know your preferred method in casting double sided coin molds. Does that moist clay / sand work the best? Dif you ever figure out the solution to cast the finest detailed silver coins?

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

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.

Skulls are cool

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.

Well, now we see for ourselves why silver coins were more often stamped than molded. Enjoyable video, thanks for including the mistakes!

Idea: cast a metal mirror, then polish them, and then compare to modern mirror.

Excellent idea.

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

you could try lost wax/pla casting since the plaster mold should have a better finish

Thanks

I think you showed why coins are struck in a die instead of cast. Looks like a lot of fun.

Nice !!! Brazilians like.

good

When making jewelry which I've done a lot casting with silver using a centrifuge to get ultra fine detail

I melt primarily for ingots but were I ever going to be creative I would rewatch your cideos with the volume up on high!

When you say pure silver is difficult to work with, what could you add to it to make it easier?
