1877 reverses are known for pronounced clash marks from the obverse die. These two examples clearly show features of the obverse (for the definition of "clashed dies" see the Varieties page). The first shows the inverted profile of the Indian, complete with nose, lips, chin and neck. The second shows the junctions where the feathers meet.
The last seven is slightly lower, with the vertical stroke more slanted and the horizontal stroke thicker than the first seven.
