I thought zinc rot possibly as well but not only is it the only place on the whole coin front and back that looks out of place.if you look closer you can tell that something was punched there because of the shadows around it showing indentation.as for see things or making images up I asked multiple people what they saw without saying what I saw and they all said the same thing.i was looking for opinions from coin collectors because none of them knows about coins as I do or at all except to spend them.lol
