I have made a bunch out of arcade tokens, I believe they were brass. They came out great, I don't believe I have any pictures of any of them though. I do have a couple token left and could probably knock one out tomorrow afternoon to show you how they look.
I might want one made out of a Casascius brass coin. How much do you charge if I send you the coins? I might also do a Silver Wallets ring (1oz silver coin).
