1950-S

The 1950-S Roosevelt dime is the San Francisco strike of the date, with 20,440,000 pieces produced in a year that saw the Mint resume proof coinage at Philadelphia for the first time since 1942. The S-mint figure is the lowest of the three 1950 facilities and roughly 44% of Denver's output, a typical mid-century ratio reflecting smaller regional demand on the West Coast. The 1950-S also stands as a meaningful condition-rare date in Mint State because survivor populations skew lower than the mintage alone would suggest, with bag-quantity hoarding less common at San Francisco in this stretch than at Philadelphia or Denver. The "S" mintmark appears on the reverse to the left of the torch base, in the Sinnock-designed branch-mint position used since 1946. The obverse carries Roosevelt's left-facing portrait with IN GOD WE TRUST and LIBERTY, the small "JS" initials at the bust truncation, and the reverse pairs the vertical torch with an olive branch and an oak branch.

The 1950-S follows the silver-era specifications: 2.5 grams, 17.9 mm diameter, 90% silver and 10% copper, with a reeded edge. Authentication on a circulation San Francisco strike begins with the weight check at roughly 2.45 to 2.55 grams in any reasonably preserved example, followed by careful examination of the "S" mintmark for clean punching without remnant of another letter beneath it. Added-mintmark fakes built from 1950 Philadelphia base coins are an occasional concern at MS-67 FB and above where premiums incentivize manipulation; a TPG slab from PCGS or NGC closes that vector. Strike quality at San Francisco in 1950 ranges from average to strong, with the Full Bands (FB) designation harder to find than on the Philadelphia or Denver coins of the same year because die maintenance was inconsistent through the year and Mint State preservation has skewed toward grades below MS-66 FB.

The 1950-S is classified Regular in the Roosevelt series and trades at modest premiums over silver melt through circulated grades and lower Mint State tiers, with sharper step-ups at MS-66 FB and above where the date functions as a genuine condition rarity for the year. PCGS and NGC populations thin meaningfully at MS-67 FB, the realistic registry-set ceiling. For broader context, see the Roosevelt Dime series history.
