No not tape. I looked again and I will go with it had something to do with glue maybe. It's PMD
I think. Looks like there was adhesive involved. Up at united it caused carosion. Sorry all. Got a box of half dollars from the bank and just getting anxious I guess. Not finding much and getting alot of 1971 72 73's, no silver and a couple impaired proofs. Probably mine that got stolen.
