1962 D LMC Doubled Eye -- Alloy And Die Pressing Question

Incuse marks on a coin is 99% of the time post strike damage. If it were a die issue, the areas in question would be raised, not incuse.

Note the metal splash away from the incuse area. That is PSD. On a struck through error the fields will not show that splash affect:
Splash affect:

Note how the metal moves away from the crater?

Struck through wire:

Note how the wire during the strike shows, but no splash as the field dies prevented this from happening.

Incuse marks on the field, or that cross from devices to field, are almost certainly due to struck-throughs or PMD. However, incuse marks on high points can be remnants of planchet marks.

High points of the coin do not receive the high striking pressure that lower points (or especially the field)do. A full strike will "fill" the die completely, with the tallest points looking exactly like the deepest parts of the die (or alternatively like the tallest points of the hub). But if striking pressure is insufficient to press the planchet metal completely into the deepest recesses of the die, those areas will look more like the planchet, and may contain scratches and such that are present prior to striking. A common area to see this is on Lincoln's shoulder. In this area, planchet marks due to a weak strike are sometimes mistaken as bag marks/hits or even rub.
