That's the point that @paddyman98 and I are trying to make. The reverse of one coin was squeezed or hammered into the reverse of another.....PMD! Chris
The OP's coin does not have PMD. It was not the victim of a vise job. Just a spot of clear glue on the reverse. Paddyman said glue, and I can stick with that too. And I dont think Wayne M will have it slabbed.
Thanks for all of your imput on this coin. It does have a blob on the back, but its not glue, it's metal.
Please post a photo of your coin after a soak in Acetone. As this is a wonderful learning experience for us all. Thanks Wayne!
I have no idea if Wayne M's is a legitimate error, but I was cleaning out my car once, and there was some change stuck in the bottom of the cup holder. I guess some soda or something leaked out of a cup and "glued" the coins together and to cup holder itself. When i pried them off and separated 2 quarters that were stuck together, this same exact thing had happened. There was a HARDENED reversed imprint of one coin on the other. It was soda.
