Found this morning, it's the second 1960D RPM I've found from the same box. I believe this one is listed on Variety Vista as RPM-015 stage B. Second image is what look's like a die chip on the right eave tip.
I'll take your word for it . With over 15 RPM's for the same year.... Congrat's ! I was never very great for those things .
Varietyvista lists 113 RPM 1960 D Lincoln Cents. Your coin looks close to RPM-015. Check the markers to see if it's the same
I believe it's RPM-015 also. One of the markers I found is the die chip on the right eave tip listed for stage B
