I am going back through my coins boxes I put away years ago, and I pulled out a box that contained some Kennedy Half Dollars and found this 1977 that has what at first looked like a cud at 9:to 11:30 on the reverse. Then I found that it extends into the breast of the eagle. Looking at the edge, which seems normal, no movement of the metal. The cross hatching of the metal looks like cheese cloth as if it is a strike through. Any ideas? It dose"t look like a lamination and it doesn't look like it is added material like sodder. Thank you in advance
Interesting, but like @Paddy54 said, it looks like PMD to me also. I do think it looks like solder that was set on something while it was still warm and pliable which made the markings.
Well, I did some research and talked to some of my family and I found out what that is. It was in a broach that was used on my wife's Grandfathers key chain. The coin came from his collection my wife inherited. Boy do I feel stupid now. Sorry to waste all of your time.
It was in interesting issue. I was intrigued by it. You learned something and that's important. No waste of time at all IMO.
