Sizes are 1.25” to 2.25”. The pair of team name buttons are c. 1950s. The four “Redskins Staff” buttons include dates of 1961 (silver anniversary), 1964 and 1968. Fourth button shows numeral “62” but we think this is a serial number rather than a date although the button also is likely 1960s. Staff buttons have very tiny raised bump caused by reverse bar pin but all six in the group are glossy and display NM to Mint. Paul Muchinsky Collection.
