1946

The 1946 Philadelphia dime opens the Roosevelt series and replaces the Mercury (Winged Liberty Head) design that Adolph Weinman had given the denomination since 1916. Congress and the Treasury approved a new commemorative portrait in the weeks after Franklin D. Roosevelt's death in April 1945, and production began on January 30, 1946, the date that would have been the late president's sixty-fourth birthday. Chief Engraver John R. Sinnock cut the dies, placing his "JS" initials at the truncation of the bust on the obverse and arranging a vertical torch flanked by an olive branch and an oak branch on the reverse, the three devices reading as liberty, peace, and strength. The "JS" placement drew an immediate rumor that the initials stood for Joseph Stalin, a story the Mint had to publicly refute and that faded only after several years of explanation in the numismatic press. Philadelphia's 255,250,000 mintage was the highest first-year output for any new United States coin design to that point and reflected the postwar need for low-denomination working change rather than collector interest in a presidential tribute.

The 1946 carries the silver-era specifications used through 1964: 2.5 grams, 17.9 mm across, 90% silver and 10% copper, with a reeded edge. Authentication on a circulation strike rests on a small set of measurable checks. Weight should land within roughly 2.45 to 2.55 grams allowing for normal wear, the reeded count should be uniform, and the relief should show the soft cartwheel luster of working-die production rather than mirrored proof brilliance. First-year die work occasionally produced softness in the torch flame's central detail and in Roosevelt's eyebrow, a characteristic the Mint corrected as the dies bedded in through the spring. Strike quality on most 1946 Philadelphia coins is average to strong, and the Full Bands (FB) designation, applied by PCGS and NGC to coins showing fully separated horizontal lines across the torch's central band, is the central condition-rarity overlay on the date.

The 1946 is classified Regular in the Roosevelt series and trades at modest premiums over silver melt through circulated grades, with prices stepping up at MS-65 FB and finer where original first-year examples with intact luster become harder to source. PCGS and NGC populations remain healthy in the lower Mint State tiers thanks to widespread set-saving when the design debuted, but full-strike upper-grade examples have always been the goal for type collectors and Roosevelt specialists.
