Still working on circulated rolls of 1956-D. It is one of the most prolific RPM dates. Here is what I believe to be RPM 1MM-003 which is a D/D North. Can anyone verify this? You can see the remnants of the old D just above the newer punched D.
Looks just like the photo on coppercoins: This is what they say: "A nicely formed upper quarter of a second D can be seen to the north of the primary minmark" Here is the link for the markers - http://www.coppercoins.com/lincoln/diestate.php?date=1956&die_id=1956d1mm003&die_state=lds
This does look like a 56D RPM-003...check out the markers in the CONECA listings for the RPM-003 and see if you can verify it. http://www.conecaonline.org/content/lincolnrpms19561957.html Larry Nienaber
