I finally pulled a Doubled Die "double earlobe" from circulation. The 1997P-1DO-001 CLASS 4 if I'm correct. Had to go through a million boxes but it paid off. Not monetarily but just to pull something. I don't see the marker on the reverse inside of the "R" though. Let me know what you think.
Sure looks like you found one :hail: http://www.coppercoins.com/lincoln/diestate.php?date=1997&die_id=1997p1do001&die_state=mds
