This will happen to me from time to time and was wondering if this has happened to any of you? When going through a roll I will encounter a coin that does this. I will first see pits all over and I actually watch them disappear over a 5 second period. There is no rhyme or reason as to when this happens. All I could come up with was moisture that evaporates. What is strange is that it will happen in the middle of a roll and the very next coin is fine. Thoughts on this?
