1921 Buffalo Nickel. MS-67 (PCGS). CAC. Beautiful frosty surfaces display iridescent toning of champagne-pink and ice-blue. The strike is fully executed, with even the most trivial design elements having intricate detail. The Philadelphia Mint reduced Buffalo nickel output by 52.4 million coins between 1920 and 1921. Despite the significantly lower mintage, 1921 nickels are available through MS-66. This issue becomes scarce in Superb Gem Mint State as offered here. From the Larry H. Miller Collection.
