Where did I put my Wayback machine?? For you youngsters out there, that is a reference to the Rocky and Bullwinkle Show and Mr. Peabody.
Just how long have you had this coin @Randy Abercrombie? Did you find it lost in one of your safes? Inquiring minds want to know.
It's probably going to need a good soak in acetone to remove PVC plastic as well. I'll go on record that coin has not been "cleaned or wiped" in a few years or so.
And to think someone passed on it at $3.00...till someone else decided to take a shot on it as priced thinking it might be a good investment
