1921-S Walking Liberty Half Dollar. MS-64 (PCGS).Fully lustrous and brilliant, the lovely light golden surfaces of this near-Gem Walking Liberty half dollar are free of distracting abrasions and display excellent eye appeal. Overall a pristine example with a bold strike that includes emerging definition over Libertys head. Although produced in greater numbers than both the 1921 and 1921-D, the 1921-S (548,000 coins struck) is the leading Walking Liberty half dollar rarity in Mint State. Jeff Ambio (Collecting & Investing Strategies for Walking Liberty Half Dollars, 2008) ranks the 1921-S as the second rarest issue of its type at and above the MS-65 grade level. The author accounts for only 150-210 survivors in all Mint State grades, such a paltry total confirming that this issue suffered a much higher rate of attrition through circulation than its 1921-dated counterparts from the Philadelphia and Denver mints. The 1921-S is also an important strike rarity, and it is only once in a very long while that the opportunity arises to acquire such a bold and attractive piece as the present example.PCGS Population: 47; 22 finer.
