1929-S

The 1929-S Standing Liberty Quarter saw San Francisco produce 1,764,000 pieces, a mintage that places the date in the moderately accessible range of late-series branch-mint issues. Strike quality on the 1929-S continued the gradual improvement seen at San Francisco through the late 1920s, with most surviving examples showing better central detail than the troubled 1926-S, though not quite matching the consistency of contemporary Philadelphia or Denver coinage. The date represents the penultimate San Francisco contribution to the series, coming just one year before the final 1930-S issue would close the West Coast chapter of Standing Liberty Quarter production.

MacNeil's mature Type 3 design appears in standard form, with Liberty standing in her gateway holding shield and olive branch on the obverse, and the flying eagle with three stars below on the reverse. Authentic 1929-S quarters weigh 6.25 grams, measure 24.3 millimeters across, and carry a reeded edge in the standard 90 percent silver, 10 percent copper alloy. The S mintmark sits on the obverse above and to the left of the recessed date, and the MacNeil M monogram appears at the base of the shield. Authenticators verify that the S mintmark exhibits the proper San Francisco punch character, with appropriate serif geometry and field integration consistent with verified examples from the same production year. The recessed date should show clean original relief without evidence of tooling, and the surrounding field should display the surface texture characteristic of genuine San Francisco strikings rather than the smoother appearance sometimes left by post-strike alteration work.

Circulated 1929-S examples trade at modest premiums above melt value, while Mint State coins follow standard grade pricing with substantial premiums attached to Full Head specimens in PCGS and NGC holders. Heritage Auctions records reveal steady availability through middle uncirculated grades and noticeable thinning at the highest tiers.
