   This is the fourth and final use of Obverse 2 and the only use of Reverse E in 1870.
Reverse E was subsequently used to strike the entire 1873-CC mintage.


Obverse 2

The following photo shows the attribution lines for Obverse 2. This die is easy to identify since itís the only obverse with the base of the 1 lining up left of centered.

Obverse 2 Die States
  1. Perfect die.
No later die states have been observed.


Reverse E

The following photo shows the attribution lines for 1870-CC Reverse E. Reverse E is the first of the two medium CC reverses. These can be difficult to separate. The second C is farther to the right on Reverse E, and thus closer to the stem. The Reverse E mintmarks are barely wider than Reverse F. The line from the feather tip to the upper right edge of the E in ONE passes through the upper serif of the first C for Reverse E, while on Reverse F it just grazes the right side of the serif.

Reverse E Die States
  1. Perfect die.
  2. Faint signs of die clashing. The most notable mark is a line extending from the tip of the upper leaf to the left wing.
Reverse E is seen only in the OC-8 die marriage. In late die states the dies began to rotate. In the latest state examples of this die marriage exhibit a 60 degree die rotation. Weíve included this end state as one of our Top-30 varieties. Our reference example of this rotation has a state b reverse. We havenít determined which came first, the rotation or the clashing. Itís possible that the dies clashed, were removed for polishing, and began rotating when returned to the coining press.
