Obverse P1 Die States

Perfect die.

No later obverse die states have been observed.

Reverse PA

1840 Reverse PA is the same die used for almost all original proofs issued through 1854. This die exhibits unique defects on A3. The photo shows these die markers, possibly created from die rust or die crumbling due to imperfect die metal. These allow easy identification of the proof die, even on mishandled or lightly circulated examples.
