Comments:   Obverse P1 was used to strike all 1852 die marriages.
This is an early use, but we’ve had no opportunity to directly compare examples of OC-1, OC-2, and OC-P1, so we can’t conclusively identify the emission sequence of those three die marriages.
This is the first and only use of Reverse A.


Obverse P1

The photo below shows the Obverse P1 attribution grid. This obverse was used for all 1852 die marriages, both business strikes and proofs.

Reverse A

Reverse A was used only for 1852 business strikes. Numerous die lines in the shield recesses and extensions of the vertical shield lines both above and below make it easy to identify. The next photo shows these markers.
