  1. Perfect die.
No later die states have been observed.


Reverse 1869 PB

Reverse 1869 PB can be very difficult to distinguish from Reverse 1869 PA., but there are a few markers that can separate the two dies. Reverse 1869 PA exhibits die doubling on the left side of the motto. Reverse 1869 PB has only very minor doubling at the top of WE, and NO doubling on IN. Reverse 1869 PB has a tiny rust pit below the edge of the scroll above the left side of the R in TRUST. These features are shown on the photo below.

Reverse PB also displays a unique scribe line along the denticles above the ST in STATES. This line is shown in the photo below.

A final marker to differentiate the two dies is the unfinished area between the lower and middle leaves. This area is much smaller on Reverse 1869 PA. The photo below contrasts the two die to show this difference.
