One of the lowest mintage issues in the popular and widely collected Walking Liberty half dollar series, the key date 1921 Walking Liberty Half Dollar was produced to the extent of just 246,000 pieces. One of the rarest issues of its type in Mint State, examples are elusive in the MS-60 to MS-64 range and seldom offered MS-65 or finer. Writing in the 2008 book Collecting & Investing Strategies for Walking Liberty Half Dollars, Jeff Ambio ranks this issue seventh in overall Mint State rarity for the type and 11th in rarity at or above the MS-65 grade level. There is an estimated surviving population of just 70 to 80 coins at the MS-65 level and fewer than 10 additional pieces in higher grades.
