   This is the only use of Obverse P1 and the first of two uses of Reverse 1840 PA in 1846 (the second use is unconfirmed). 1840 Reverse PA was used for almost all
original proofs from 1840 through 1854.

Obverse P1

The full date is repunched, with the original punch almost half the date height too low. The original date
was then effaced and repunched in the proper position. The following photo shows the repunching.

- Perfect die.
No later die states have been observed.

Reverse 1840 PA
The reverse die used for the 1846 proof issue is the same die used for almost all proof issues through 1854.
This die exhibits unique features on A3. The following photo shows these die markers, possibly created from
die rust or just die crumbling due to imperfect die metal. These allow easy identification of the proof die,
even on mishandled or lightly circulated examples.
