3.5" w/concave metal back. No pin. Unlisted in Hake. Some lightness along the right edge of the design, as well as just under McKinley's ear. Scattered separations along back curl that do not affect display. Technically Fine, but displays well above grade. We've encountered this design in smaller sizes 7/8" and 1.25" as well as a matching Bryan but this is only the third of the large variety we can recall in our 58 years. John Gearhart Collection.
