This die is easy to identify since itís the only die that has the date centered vertically in the field. All other 1840 obverse dies have a date thatís higher. Obverse P3 is also characterized by several concentric die lines in the gown right of the shield. The most notable of these lines is indicated by the arrows in the attribution grid photo.

Reverse PC

This reverse is designated as PC since it was first used to strike proofs. It exhibits several vertical shield lines extending into the horizontal lines. Compare to reverses A and B, where the only major extensions are the three lines in the first group. The other marker is the LACK of the markers exhibited by reverses A and B - no extensions of the vertical shield lines into the shield border at the bottom.
