Comments:
   This is the only use of Obverse P1 and the only use of Reverse 1866 PA in 1867. Reverse PA is transitional, used to strike at least one proof die pair in each year from 1866 through 1870.


Obverse P1

Obverse P1 shows no obvious die markers, but the date position is significantly higher and farther right than the business strike die, and NO date repunching is evident. The following photo shows the Obverse P1 attribution grid.

Reverse 1866 PA

Reverse 1866 PA can be quickly identified by the heavy die line under GOD in the motto. Lesser die lines are visible passing through the center of N and the center of WE. Numerous die lines and lumps are also visible in the unfinished areas around the leaves. These are shown in the photos below.
