Comments: This is the only use of Obverse P1 and the only use of Reverse 1840 PA in 1854. Reverse 1840 PA is the reverse die used for almost all original proofs from 1840 through 1854. This is its final use. |
Obverse P1 The photo below shows the Obverse P1 attribution grid.   1854 Obverse P1 attribution grid This is the only original proof obverse die. It exhibits no obvious die markers, but the combination of a normal date, with no repunching, and its marriage to 1840 Reverse PA is enough to make attribution easy.

The reverse die used for the 1854 original proof issue is the same die used for almost all original proof issues from 1840 through 1854. It exhibits unique features on A3. The photo below shows these die markers, possibly caused by 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.  Reverse 1840 PA defects in A3
