Largest is 2.25"/smallest 7/8". First reads "Student Nonviolent Coordinating Committee" around edge and "We Shall Overcome" at center. Scratching consistent with light use and bump from bar pin back just above the "LL" in "Shall". Fine. Second reads "One Man One Vote SNCC". Light stains on collet not extending to the front and small indentation on the "N" of "Man" at the extreme edge. VG. Last reads "SNCC" with black and white hands clasp in handshake. Not quite .25" air mark just beneath center seen in reflected light. VF. A nice group of early to mid 1960s relics.
