Attached are 2 photos of a 1960 Double D Cent that I just cataloged. Found in circulation in the 60's.
Nice RPM. Looks like: http://coppercoins.com/lincoln/diestate.php?date=1960&die_id=1960d1mm049&die_state=mds
A quote from the link "This variety shows a very strongly punched southeast spread. It is one of the strongest of all 1960D southeast spread mintmark varieties." This punch is to the SE. Do you think it competes with the one in the link? Or, do you think it is a different variety?
