Tell us about yourself!
Right after I posted, I noticed that you've tackled this issue before! I've found several sources, which cite US law, on both counts, but figure with so much confusion, the penny-police won't be showing up any time soon! (Besides, they'll visit the carnivals and the "penny collector" people first anyway!) Some relatives used to make rings out of quarters years ago, and strangely, I just found a couple of them yesterday! Go figure! I tried to vote for you, btw, but the contest ended. You have a winner here! I'll let you know how mine turn out! Thanks for such a great tutorial!
