Damn man! Looks great! Wouldn't mind having one for myself. You could print the coins out with a code on the back, that's hooked up to a faucet, then when you type the code into the faucet you get some GRC sent to your address. It would be a great gimmick to promote Gridcoin at events and such.
Physical Souvenir + Free GRC = Great Time
