1921-D Walking Liberty Half Dollar. MS-65 (PCGS). This is an overall pearly and brilliant Gem with scattered bronze iridescence accenting the peripheries. A beautiful matte-like texture dominates the fields, complementing the rich frosting across the devices. Delightful to examine in-hand and fully without distractions. <p>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 example represents a particularly significant opportunity for Walking Liberty half dollar enthusiasts. Just 6 examples have been certified finer by PCGS through MS-66, stressing the true conditional rarity of this issue. An ideal PCGS Registry Set candidate.
