I think you are talking about die 4 listed on CONECA, right? It has two different numbers on coppercoins, but should be the same coin cross referenced. It's a proof DDO & DDR. Coppercoins has it at $100 @ PF65. Here is the link. It has the values and pics for comparison. http://www.coppercoins.com/lincoln/diestate.php?date=1955&die_id=1955p1do007p&die_state=mds
