1921-D

At 208,000 coins struck, the 1921-D Walking Liberty half dollar holds the title as the lowest-mintage business strike in the entire series, making it the undisputed apex key for date and mintmark collectors. Denver's involvement that year was minimal because the Treasury had no operational need for additional fifty-cent pieces after the Pittman Act silver consumption, and the Mint moved on to other priorities within months. The coins that did leave the Denver vault entered circulation in pockets, change drawers, and small banks across the Mountain West, where many were spent into oblivion before numismatists organized any meaningful save. Survivors today are concentrated in the lower circulated grades, with Mint State pieces representing perhaps a few hundred examples across all grading services combined.

Strike quality on the 1921-D is generally acceptable for the date, though softness on Liberty's hand and the eagle's central feathers is common. The mintmark sits at the lower left of the reverse near the eagle's tail and rock, and its punch style is the small serifed D used at Denver during the period. Genuine 1921-D mintmarks display a specific spacing and tilt that altered coins rarely replicate, so any purchase above the few-hundred-dollar range demands microscopic comparison against published reference photos. Counterfeiters most often attack this date by adding a D to a genuine 1921 Philadelphia coin, leaving telltale tooling around the mintmark, a slight raised ring, or a mintmark sitting on top of original field rather than rising from it. Verify weight at 12.50 grams, diameter at 30.61 mm, and confirm a reeded edge struck through to the rim. Cherrypickers' Guide lists die markers on the reverse rock that are reliable confirmation aids when present.

Auction history on the 1921-D is dramatic. Heritage Auctions has crossed six figures multiple times for choice and gem Mint State examples, with the finest known coins approaching or exceeding a quarter million dollars at MS66 and above. Even well-worn Good and Very Good pieces command four-figure prices and have appreciated reliably over the past two decades. Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) certify the date sparingly, and registry-set competitors guard their examples closely. No serious Walker date collection is complete without it. Read more in the Walking Liberty Half Dollar series history.
