15/16” with rows of raised circles plus a flatter inner band with almost microscopic circles surrounding an extremely clear image of him with his name below although positioned so that most letters of his last name are only partially visible. Reverse has a convex tin cover with a solder dot at center holding a 1-1/8” vertical stickpin. Some loss of the luster from the brass but the emulsion displays essentially mint and in fact is NM with only a virtual pinpoint black dot or two showing under magnification. Rare and seldom offered.
