1827 O-122 R5

Obverse: Star 1 points to lower edge of dentil. Wide date has the 2 low. This is a LDS use of the obverse die, so the stars are drawn to the edge, and there is little milling. (Obverse shared with O-121, and O-123.)

Reverse: there are two strong die lines starting from the eagle's head near the opening of the bill and at the base of the bill. They go through the left wing and into the field beneath the left wing.
