1840 Obverse P2 attribution grid

Obverse P2 was used to strike both proof and business strike issues, our die marriages OC-P2, OC-P3, and OC-3. OC-3 and OC-P3, which share the same reverse, are both found with a counterclockwise die rotation of about 10 degrees, indicating they were probably struck at the same time.

Reverse PB

Reverse PB is identified by the extension of vertical lines 1-2 and 1-3 into the horizontal shield lines and by the penetration of lines 2-3 and 3-1 into the shield border. These markers are shown in the photo below. As with the corresponding obverse die the reverse is designated as PB since it was first used to strike proofs.
