Unfortunately there is a huge problem spot on the ... umm ... reverse? I don't even know which side to call the obverse and which the reverse. I'm wondering if there is something I could do to remove the tainted portion, or if that is even a good idea, or even if it's worth bothering about. I know that unfortunately some of the design elements on the token are forever gone whether I clean it or not. I don't know if you can tell from the pictures but the area around the edge of the spot has that green tarnish that you see on old copper that has been weathered. I'm not sure how long this spot has been there as it's been stored for decades since I last pulled it out and I don't remember if it's always been there or not. So, any thoughts on the problem spot? Does anybody recognize this token that could tell me more about it than I already know? I admit I haven't done my due research on it yet, like I said I just recently figured out what it actually was.
