1896-S Barber Quarter. AU Details--Environmental Damage (PCGS). Muted by dusky sandy-gray patina to explain the PCGS qualifier, the surfaces are actually quite smooth in hand and boast considerable sharpness of detail throughout the design. Among the trio of key date Barber quarters from the San Francisco Mint, the 1896-S is eagerly sought at all levels of preservation. From the Lincoln Square Collection.
