1921-D Walking Liberty Half Dollar. MS-64 (PCGS).Offering bolder striking detail to the high points and more warmly toned surfaces than the coin in the preceding lot, this 1921-D will likely appeal to a different subset of advanced Walking Liberty half dollar enthusiasts. Both sides are bathed in light pewter and medium golden-gray patina that blends nicely with soft satin luster. The centers have emerging to bold detail, as does Libertys head, and the balance of the features are sharp. Seldom do collectors have the opportunity to choose from multiple Choice Mint State examples of this key date issue in the same sale, for they are scarce in an absolute sense and quite rare under normal market conditions.PCGS# 6584.
