The original 'non-counter stamped' specimens would naturally be a little larger in diameter, being they were struck from sheet metal planchets. Maybe thinner, too. When cast, the poured metal shrinks a bit. My repro measures 22.95-23.3 mm dia. X 1.7-1.85 mm thick. Having been cast repros with the Becker counter stamp at least lets you know they were not meant to deceive. Even as repros, they're not often seen for auction. Still worth collecting, IMO
