Thank you Chris, RWB, and Bob.
Sorry to hear that cross-overs are not more straight forward. In the end I desire a common appearance for display but may settle for an NGC and PCGS split. A slight variation to my earlier question, if PCGS graded my coin XF40 in the late 90s, is there a good chance it would grade the same today?
RWB, there doesn't appear to be an issue with the coin at the 2:00 position. This early generation PCGS holder has plastic tight against the coin full 360deg and what you note as an irregularity at 2:00 is on the PCGS slab. The coin denticles define the perimeter, the smooth ring just outboard the denticles is actually the slab. Then again, I really can't study the perimeter so I guess there could be an issue at 2:00
Bob, the website you linked to is perfect, thank you!, O-116 it is. Some of these early coin variations are neat, adds another dimension to collecting them. I've identified some half cent die variation favorites that I'll be keeping an eye out for.
