I know this one has seen better days, is this a lamination crack and loss of laminations on the reverse? The mm placement does match the DDO.
Here is a RPM that I can't seem to match this would be a D/D south. I imagine it is one of them just in a different die stage. Also has a very weak UST.
Ghostly looking coins are really neat IMO. It can add a lot of character to an otherwise blah coin. Fun find
Heres an unusual die crack on an 83 Lincoln. It runs from the rim N of united to the memorial roof, along the cornice ending at the 8th pillar.
