Obverse: Star 1 points to lower half of dentil. There is a die line starting below the headband under L at right, extending up into cap. On this late use of the die, many stars still show recutting, most obvious on stars 7, 11, and 12. 2 has a tall serif on its base. (Obverse shared with O-131 & O-148.)

Reverse: there is a line in the field placed diagonally just outside the eagle's breast just above the far right claw.
