1886 Liberty Seated Quarter. Proof-66+ (PCGS). CAC.A superb Gem with prominent shades of rich blue and magenta toning on both sides. Firmly struck with bold centers and lively luster in the fields. An aesthetically pleasing specimen showcasing impeccable quality. One of the more eagerly sought Proofs in the Liberty Seated quarter series, the 1886 is usually 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.
