Comments: This is the first of two uses of Obverse P1 and the only use of Reverse 1840 PA in 1849. Reverse 1840 PA is the die used to strike almost all original proof issues from 1840 through 1854. |
The next photo shows the Obverse P1 attribution grid.   1849 Obverse P1 attribution grid Obverse P1 has few notable markers, but the date position is farther right than Obverse 1, so it's relatively easy to separate the two dies.

The reverse die used for this 1849 proof issue is the same die used for almost all original proof issues from 1840 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.  Reverse 1840 PA defects on A3
