Good evening. Hunting rolls I came across this Idaho
State Quarter. The obverse is normal considering it's been in circulation. The reverse has multiple little dots all over it. It feels it too. Running my finger across I can feel them. I soaked it in acetone thinking glue or whatnot but it did not come off. I took a q tip and rubbed it with warm water and light soap. Still there. It is in the coin. It looks like a type of fabric and feels the same. I know you guys can look and tell me if it's my mind playing tricks or is this struck through cloth? Thanks and God bless. Happy hunting everyone!
