Found this in a bank roll. Not sure what I'm looking at. I've seen half dollars take on some golden hues when stored with clad coinage over extended periods, but more commonly on the 40% silver halfs. Is this just odd toning? Or, was this gilded or dipped at some point and the plating is coming off? Or is there some minting error at play here? There also appears to be a die crack along the outer edge of the word "Dollar".
The reverse has glue on it. That’s what looks golds and looks like a crack. This coin was glued to a paper or something. Should come off with either a hot water rinse or acetone. Nice find.
