This is the only business strike use of Obverse P1 and the first or second use of Reverse 1848 A in 1850.
Obverse P1 was also used for to strike the OC-P1 die marriage. Reverse 1848 A was used previously in 1848 and 1849
and subsequently in 1851. It was used in 1850 to strike OC-1 and OC-P2.
Obverse P1 is the only business strike obverse die. It exhibits notable repunching on the 0, most visible on the lower
left side of the prominent digit. Die lines slant very slightly up to the left from the denticles below 50.
The following photo shows the Obverse P1 attribution grid, with arrows indicating the other features.

Reverse 1848 A
This reverse was well-documented in our article in issue #120 of the Gobrecht Journal (reference 11). Most of
the features described for die states a through d of this reverse are gone in 1850. State e exhibits a new major
die line, pictured below, extending through the right side of the horizontal shield lines and across the right
shield border into the feathers. Presence of this die line makes attribution easy.

Reverse 1848 A Die States
See 1849 OC-1 for a full description of die states a through d. Only die state e has been found in 1850.
State e -  A notable die line slants down through the right side of the horizontal shield lines, extending very slightly
into the feathers on the right. This die line is apparently the result of work on the die which occurred after its
use in 1849 and before its use in 1850.
