Not sure what this is, and there are no markings. Rang up like an old copper coin, had crust like an old copper coin, and thought it might be a copper coin until I cleaned it. Oh well. Looks like it may have a Co, but that's probably a mark from it being smashed on the edge of something. Same size (1 1/8") as old large copper coins, although a bit thinner. Anyone have any idea?
