2.25” with very young photo of Humphrey with illustration of U.S. Capitol at left. Lower center has extremely shallow dent with just a barely visible pinpoint nick on the bottom rim edge. Reverse has tiniest trace of stain on the brass colored metal back along the curl edge but this causes no problem. Curl is marked with name of maker “Wendells, Inc. Minneapolis.” Button still displays Mint. From the Morry Greener Collection.
