1907-S

San Francisco's 1907-S Barber half came out at 1,250,000 pieces, the lowest 1907 production across the four operating mints by a substantial margin. The S mintmark sits above the eagle's tail feathers on the reverse in the standard Barber-half location. The 1907-S entered commerce alongside Philadelphia's 2,598,575-piece run, Denver's 3,856,000-piece second-year output, and the larger 3,946,600-piece New Orleans total. The 1.25 million figure puts the issue notably below the routine multi-million output of contemporary San Francisco runs, and the date carries a measurable scarcity premium above the common-date tier without ranking as a Semi-Key on most catalog systems.

Strike on the 1907-S is the central collecting concern for the date. San Francisco dies in this stretch produced halves with notably soft detail on Liberty's hair above the ear, the wreath leaves on the cap, and the eagle's claws and leg feathers. Heavy die wear shows up on a meaningful portion of the population, and collectors pursuing Mint State examples should examine multiple coins to identify pieces with full strike. The LIBERTY headband functions as the working grade indicator, but the date's strike weakness can make AU and lower Mint State grades visually disappointing relative to the technical assignment. PCGS, the Professional Coin Grading Service, and NGC populations cluster through Good, VG, Fine, and VF, with a falloff through XF and a thin population above MS62. Authentication runs the standard checks: 12.50 g weight, 30.6 mm diameter, reeded edge, with a mintmark inspection to rule out an added S punch given the modest but real premium attached to higher-grade survivors.

The 1907-S sits as a slightly better-date San Francisco Barber half, trading at prices above common-date levels through XF45 and stepping up meaningfully into the Mint State grades where supply thins. Collectors pursue the date through a 1907 four-mint set or a complete San Francisco Barber half run, with strike-quality screening essential before any MS63 or finer purchase. A problem-free XF or AU example with above-average strike represents a strong value for collectors who prioritize eye appeal over technical grade.
