I have been looking at this MM for awhile. After doing some research I think this 1939s penny is a RPM- 002. I would appreciate your input! Thanks in advance! Q
IMHO it looks more like Wexler's WRPM-004. Check it against the one on his site: https://doubleddie.com/967399.html I can only judge by the photos you posted. It's much easier with the coin in hand.
