This RPM is not on VV, I was originally thinking RPM-014 but the S is too low, and the abraded die is not present. I haven't checked Wexler yet. These 2 have nearly the right placement. https://coppercoins.com/lincoln/diestate.php?date=1950&die_id=1950s1mm022&die_state=mds I leave towards 1MM-026 Just in an earlier die stage. https://coppercoins.com/lincoln/diestate.php?date=1950&die_id=1950s1mm026&die_state=lds
So I was able to get it under my scope again. It does have a small die chip above the 5 and die scrapes leaning towards Lincolns chin. Large die chip next to the "N" in "IN". I do not see any matching this one.
