Comments:
   This is the second of two uses of Obverse P1 and the second of two uses of Reverse PA.
Both dies were first used to strike 1860 proofs.

Obverse P1
The photo below shows Obverse P1 attribution grid. Obverse P1 exhibits no significant die markers,
but the date position should be adequate for definitive attribution.

Obverse P1 Die States
- Perfect die.
No later die states have been observed.

Reverse PA
Reverse PA exhibits light die lines in the upper shield recesses, shown in the following photo.
These lines are light, and may be hard to see, particularly on the OC-6 business strikes. The
die was polished after the proofs were struck, significantly diminishing the definition of the
die lines. The die line at the top of shield recess #6 is the most visible after the polishing.

Reverse PA Die States
- Perfect die.
No later die states have been observed. Most examples seen have exhibited a counterclockwise die
rotation of approximately 10 degrees.
We’ve found no conclusive method for separating proofs from business strikes. It’s a judgement call
based on surfaces and strike characteristics.
