1921

The 1921 Walking Liberty half dollar carries a mintage of just 246,000 pieces from the Philadelphia facility, the second-lowest production figure across the entire series and one of the most heavily pursued business strikes of the twentieth century. Output collapsed because the Pittman Act melts had glutted the channels with new silver dollar production, leaving little Treasury appetite for half dollars. When the Philadelphia presses did roll, they produced a coin that almost immediately disappeared into circulation and was hoarded by date collectors who recognized the rarity within a year of issue. Survival rates in circulated grades are reasonable, but anything approaching Mint State is genuinely difficult, and gem examples are well beyond the reach of casual buyers.

Strike on the 1921 is generally better than the San Francisco issue of the same year, but the central design devices, particularly Liberty's left hand and the eagle's breast feathers, are routinely soft. Authentication is the first concern for any buyer above About Uncirculated. The most common deception is the addition of a D mintmark to a genuine 1921 Philadelphia coin in an attempt to create a 1921-D, so any 1921-D candidate should be cross-checked against this date's known reverse die markers. Weight should sit at 12.50 grams plus or minus normal tolerance, with a 30.61 mm diameter and reeded edge consistent with the .900 fine alloy. Cherrypickers' Guide notes a recognized doubled-die obverse on the date that shows on LIBERTY and the motto, useful for confirming an unaltered original surface. Examine the field around the date for tooling or hairlines that suggest a date has been re-engraved over an altered host.

Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) populations thin out quickly above MS64, with gems trading into five figures at major auctions. Heritage Auctions has recorded multiple MS66 appearances climbing past forty thousand dollars in recent years, while MS67 examples are nearly unobtainable on the open market. Circulated examples from Good to Fine remain accessible entry points, though all 1921 dates have appreciated steadily over the past decade. The issue is required for any complete Walker date set and anchors short-set extensions that go beyond the popular 1941 to 1947 run.
