Obverse 4

The following photo shows the Obverse 4 attribution grid. We refer to this as the “bar 6” variety. The arrow points to the bar which extends from the upper right side of the loop of the 6 across the ball and slightly into the field. It appears to be a slip of the engraver’s tool rather than an under-digit.

Obverse 4 Die States
  1. Perfect Die.
No later die states have been observed.


Reverse 1864 A

Reverse 1864 A displays faint extensions of the first 3 vertical shield lines, shown in the following photo, that allow definitive attribution for mid- to high-grade examples.

All 1865 uses of Reverse 1864 A display a die crack across the top of many of the letters. The crack joining ER is notably irregular and can be used as an additional marker. This is shown in the photo below.
