1921-D Walking Liberty Half Dollar. MS-64 (PCGS). CAC.With its bold to sharp strike and appealing mint luster, this lightly toned near-Gem half dollar is sure to find its way into an advanced collection. The 1921-D has the lowest mintage among Denver Mint Walking Liberty half dollars with just 208,000 pieces produced. A key date issue for its type, only the 1919-D, 1919-S and 1921-S are rarer in terms of total number of Mint State coins extant. With precious few Gems known, this premium quality MS-64 represents a particularly significant opportunity for Walking Liberty half dollar enthusiasts. A lovely coin that is sure to sell for a strong bid.From the High Rise Collection.
