Octagonal copper alloy sleeve buttons with decoration in a circle within circles pattern.  One shank has worn through. Although most copper alloys form green corrosion in the ground, this button looked gold when it was found. The brassy color was preserved by the unique soil chemistry of the tannery; leather and wood also survived.
