Hi,
I am wondering if anyone knows any online shops that sell copper blanks (to make your own coins). I'm in the mood of trying this experiment out over the holidays. Just my initials or a small design on copper.
Thank you!

On the site childofthewheat mentioned they sell 19mm (cent sized) copper blanks for 56 cents each. Now those are type 1 style blanks and at 24 gauge they are thinner than a Lincoln Cent. https://www.beaducation.com/zen_products/1780They do have thicker 18 guage blanks which would be more like the thickness of a cent for 75 cents each. They say they are sold out at the moment. https://www.beaducation.com/zen_pro...3-4-19mm-18gChute72's site only does copper sheet so you would have to be able t punch your own blanks, and then what do you do with the scrap? |

https://www.beaducation.com/zen_pro...m-circle-20gSelling silver blanks under spot?! Spot for .999 silver is $.45 per gram So if this is really 20 grams, the fine silver blanks would be worth $9 in silver weight alone...looks like something is awry. Or...  Let's get rich off of them!

If you have a punch, the scrap may be less than the mark up for pre-punched. A lot depends on your tools and labor schedule.
The 7/8" discs aren't 20 grams, they're 20 gauge. That works out to be about $1.50 per disc at today's silver prices.

Lol I'm pretty sure 0xDA71D was just messing around with us.
Thank you for the sites guys. I might just order a few from beaducation and if I like the idea of making my own coins, I'll look into sheets and a puncher

0xDA71D: I believe the 20g means 20 gauge, which is the thickness. their weight is unlisted, but most likely in the 1-2 gram range.

Or use US pennies, like a counter stamp

Ops, my mistake on the 20 guage coin
You could just try flattening pennies. Maybe roll them under a large roller press. Press it in multiple directions and you will get a reasonably round planchet, albiet very flat and thin.

The volume of the disc can be determined from the 7/8" diameter and .032" thickness.
The density of silver is 10.5 grams/cm3.
The weight is 3.31090 grams
If I've done my math correctly.

For that price, just put some cents on the railroad tracks. Or just get some of the punch outs from metal electrical boxes. Pretty good slugs to play with, although steel doesn't squash quite as well as copper. At least on train tracks. Yes, as a youth I did some minor counterfeiting.  They really jump on Liquor tax stamps, though. Whiny babies should have hired me to improve their security (at 14). Well, it was 1968. I was tight on data systems when I was in the U.S. Navy, just couldn't get above a 'Secret' clearance. I was backward engineering crypto gear in my spare time.... Meh, I never looked for a back door at that time. http://www.wired.com/2013/09/nsa-backdoor/TL;DR The NSA has insisted that a flawed random number generator be available in devices. Even though most everybody uses a different RNG in their devices, it is simple for the NSA to change a suspects RNG to the flawed one. Making the suspects encrypting an open book. Sigh, time doesn't fly, it uses warp drive. |
