Notes:
The O-108 is a doubled die error reverse. There is doubling on the upper side of the left wing tip to to the left of all three claws and the left talon. The doubling is strongest  on the three lower pairs of leaves, berries and berry stems of the olive branch. Light doubling is seen on the second and third talons and back of the two lower arrowheads. This was caused when the hub (which consists of the eagle/arrows/olive branch image) was a little off during the second impression into the die.
