This looks to be a new (or at least not in the most recent cherrypikers guide) 1951 d/d. Since I am rather new to RPM's and my new microscope, I though I would seek some validation. Please let me know your thoughts.
really difficult to see anything for certain. Have you looked at it through a loup and under a good light?
I'm not saying that it is not a D/D but it looks more like a post mint damage. Without better pictures it is hard to say what it is.
There are no die cracks that I have found, obverse or reverse. In looking at this at 60x I clearly see the seperation at ends of the D. I wish my camera was better so I could get a clear microshot.
