1921-S Walking Liberty Half Dollar. MS-62 (PCGS).Brilliant and virtually untoned, with just a faint golden shimmer visible beneath direct lighting. The luster is uniform and nicely composed, enhanced by die polishing throughout the obverse fields. Attractive and absolutely choice for the assigned grade. <p>Although produced in greater numbers than both the 1921 and 1921-D, the 1921-S is the leading Walking Liberty half dollar rarity in Mint State. Of the 548,000 coins struck, perhaps just 200 remain across all Uncirculated grades. Specialist Jeff Ambio ranks the 1921-S as the second rarest issue of its type at and above the MS-65 grade level, though demand remains overwhelming at all Mint State grades.PCGS# 6585. NGC ID: 24R8.
