The 1921-D Walking Liberty Half Dollar has the lowest mintage for the series overall, but the 1921-S Walking Liberty Half Dollar emerges as a greater rarity in higher grades.
All three issues for 1921 have low mintages with 246,000 coins struck at the Philadelphia Mint, 208,000 coins struck at the Denver Mint, and 548,000 coins struck at the San Francisco Mint. Each of the coins carries premiums in circulated grades, led by the 1921-D.
In higher circulated grades and uncirculated grades, the 1921-S Walking Liberty Half Dollar emerges as the highest premium coin. Most examples of this issue are weakly struck, making better strikes in great demand by specialists. A few dozen gem examples exist, a number which most likely includes several resubmissions as auction appearances are scarce. PCGS and NGC have both graded just a single MS-66 piece, with none finer.
