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. Our own Jeff Ambio (Collecting & Investing Strategies for Walking Liberty Half Dollars, 2008) ranks the 1921-S Walking Liberty Half Dollar as the second rarest issue of its type at and above the MS-65 grade level. He accounts for only 150 to 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.
