Can I make a suggestion .Don't clean any coins or possible coins before having guys on here give an opinion on what it is, you could scrub a real valuable coin into being not so valuable.I mean each to his own, but it would make you sick if you found something old and valuable and you took all the patina off by cleaning it, making it practically worthless, we all have probably done it. I know I cleaned a Roman coin and to this day I kick myself for doing that.
