1886 Liberty Seated Quarter. Proof-66 (PCGS).A richly original specimen, both sides exhibit intermingled highlights of pale pink, blue-gray and antique gold to dominant charcoal-copper patina. Appreciably mirrored in finish with a full strike to virtually all design elements. One of the more eagerly sought Proofs in the Liberty Seated quarter series, the 1886 is associated by date and issuing mint with a circulation strike issue that saw just 5,000 coins struck. Proof mintage for the date is 886 pieces, and the present survivor is finer than most.PCGS Population: 31; 12 finer in this category (Proof-67+ finest).
