I enlarged and sharpened the OP's photo.

The mm is too far east for OMM-001 and too far north for OMM-002. The mm position (and what appears to be a long die crack on Lincoln's lower shoulder to the lapel) more strongly suggest RPM-012. That said, the date and mm are affected by MD, and the mm has also taken a knock in circulation, and those could well explain what is seen here.
