1913-S

San Francisco's 1913-S Barber half ran 604,000 circulation pieces, the second-lowest 1913 issue across the three operating mints and one of the lower San Francisco outputs in the Barber half series. The S mintmark sits in the standard Barber-half location above the eagle's tail feathers on the reverse, between the tail and the period after AMERICA. The 1913 production year sits at the front edge of the steep mintage drop that defines the close of the Barber half run, with Philadelphia at 188,624 and Denver at 534,000 bracketing the 1913-S above and below. The issue earns Semi-Key classification on the site and a strong condition-rarity reputation through Q. David Bowers and PCGS CoinFacts.

Strike on the 1913-S runs to the softer end of typical Barber half quality, with weakness common on the eagle's claws and on the upper wreath leaves on Liberty's cap. The LIBERTY headband on Liberty's cap functions as the standard wear indicator: the letters L and I wear first, and their full presence supports an AU45 or finer assignment. PCGS, the Professional Coin Grading Service, and NGC populations cluster through Very Good and Fine, thin sharply through XF and AU, and become genuinely scarce above MS63. The condition-rarity profile is real: certified gem examples are uncommon enough that Heritage and Stack's Bowers auction archives show MS65 results trading at multiples of the routine common-date Barber half price band when they appear. Counterfeit risk is moderate; the canonical alteration pattern on the issue is removal of the S mintmark to create a false 1913 Philadelphia Key Date. Authentication should include the standard 12.50 g weight check, the 30.6 mm diameter verification, reeded edge inspection, and a careful look at the reverse field above the eagle's tail for tooling marks that would betray a removed punch.

The 1913-S sits among the stronger Semi-Keys of the Barber half series and trades at meaningful premiums over the routine common-date band across every grade. Circulated examples remain accessible to series-completion collectors at fair prices through Fine and Very Fine, while Mint State certified examples become the focus of serious specialist demand above MS62. PCGS or NGC certification is strongly preferred over raw coins for any Mint State purchase given the alteration risk and the condition premium at the top of the grade ladder.
