I give up on this one. I'm guessing it's a Spanish coin, perhaps 1 centimo, but I can't find anything in my World Coins books nor on the web to compare. It's about 23 cm; the other side (obverse?) is worn completely slick. You can see a hint of a few letters around the edge, but I can read only the date. If anyone has a link to a decent image of it, I'd appreciate your posting it. Thanks in advance.
