Why would you do this to a coin...?
Yes, I'm the one who once asked "why would someone paint silverware?. So now I'm asking why would you take a pretty worthless, though old, coin, and turn it into a...um, what is this? I think it's just another bit of decorative junk my grandmother picked up on a trip somewhere. She thought it was used for checking wine at a winery (someone must have told her that--she certainly wasn't in the wine business) but I don't think you'd do that with a nasty-tasting copper or bronze coin. So,
what is it!?? It's about 4" across and an inch deep.
