1964 Washington Quarter. MS-67+ (PCGS).Impressive condition rarity from the final year of the 90% silver circulation strike Washington quarter series. Fully frosted in finish with a virtually pristine appearance, the otherwise brilliant surfaces are further enhanced by blushes of light copper-russet peripheral toning. Sharply struck. This is obviously a plentiful issue in an absolute sense, the Philadelphia Mint churning out 560,390,585 quarters for commercial use in 1964. Many are the Mint State coins in numismatic and non-numismatic hands, although precious few can compare to this upper end Superb Gem in terms of either quality or eye appeal. Tied for finest certified at PCGS, in fact, and eagerly awaiting inclusion in a top tier Washington quarter set.
