Here are some of the other varieties I cherried today. 1955 Proof DDR I believe Die 3 1951 S/S RPM-003 1943P RPM-037
LOL! No I don't know the markers by heart, I just look them up in the RPM book when I get home. I knew it was an RPM but of 51S rpm's 1,2&3 are very simular these die markers are they only way for me to tell the diference.
