Comments:
   This is the first of four uses of Obverse P1 (the fourth use struck business strikes) and the only use of Reverse 1869 PA in 1870. Reverse 1869 PA is transitional, used previously in 1869 to strike 1869 OC-P2 and OC-P3.

Obverse P1 Die States
  1. Perfect die.
  2. light die clashing visible under the rock.
No later die states have been observed. State b has only been seen on a single coin. Itís apparently very rare. The clashing probably ended the run of this die pairing.


Reverse 1869 PA

Reverse 1869 PA has no obvious markers, but it does display minor die doubling thatís visible on the left side of the motto and on the adjacent elements. This doubling is indicated by the arrows in the photo below.

The areas around the leaves are almost completely finished on this reverse, whereas the other two reverse dies used for proofs in 1870 show significant unfinished areas around the leaves.

Reverse 1869 PA Die States
  1. Perfect die.
No later die states have been observed. This die marriage has been seen with die rotations of up to 20 degrees. The rotated die examples don't seem to be particularly rare.
