1939-S

San Francisco produced 10,540,000 Mercury Dimes in 1939, a smaller share of the total annual coinage than its sister mints and a figure that makes this date somewhat scarcer than the Philadelphia or Denver issues. The coins entered West Coast circulation channels and stayed in active use for years, paying for movie tickets, soda fountain treats, and other small purchases through the war years. Mint State examples exist in respectable numbers because collectors and dealers set aside rolls during the 1950s and 1960s, but Full Bands strikes are notably scarce on this date and command considerable premiums.

The Weinman design features Liberty in her winged Phrygian cap on the obverse with the date below and IN GOD WE TRUST left of the bust. The reverse displays a fasces with an axe head at top, wrapped diagonally with a thong and flanked by an olive branch, with the S mintmark at the lower left of the fasces base. The coin weighs 2.5 grams in 90% silver and 10% copper, measures 17.9 mm across, and has a reeded edge. Authenticators on 1939-S check the S punch shape, which should be the knob-end style used at San Francisco in this era, and inspect the central horizontal bands on the fasces for the complete separation required by PCGS and NGC for the Full Bands designation. The wing details on Liberty's cap also reveal strike strength.

The date is affordable in circulated grades and through MS-64, with prices stepping up at MS-65 Full Bands and climbing steeply at MS-66 FB. Heritage Auctions records confirm strong demand for top examples. Roll-quantity finds from estate consignments occasionally bring fresh material to the market, though such groups are increasingly uncommon. Original surfaces with consistent luster across the cheek, wing, and reverse fields are the strongest signal of long-term holding value. See the Mercury Dime series history for broader context.
