1948

The 1948 Philadelphia Roosevelt dime is the third year of John R. Sinnock's design and the first full calendar year of dime production after Sinnock's death in May 1947. Working dies for 1948 were sunk from the original Sinnock master hub, and the design carries forward without modification through the transition to the next Chief Engraver. Philadelphia produced 74,950,000 coins for circulation, a 38% drop from the 121,520,000 figure of 1947 as the Mint adjusted output to match settled postwar transactional demand. The obverse carries Roosevelt's left-facing portrait with IN GOD WE TRUST and LIBERTY, and Sinnock's "JS" initials at the bust truncation; the reverse pairs a vertical torch with an olive branch and an oak branch, the three devices reading as liberty, peace, and strength. No proofs were struck in 1948 because the Mint's proof program had been suspended in 1942 for wartime conservation and did not resume until 1950.

The 1948 follows the silver-era specifications: 2.5 grams, 17.9 mm across, 90% silver and 10% copper, with a reeded edge. Authentication on a circulation strike begins with the weight check at roughly 2.45 to 2.55 grams in any reasonably preserved example, followed by inspection of the reeded edge for uniform spacing and examination of the obverse fields for the cartwheel luster of working-die production rather than the mirrored brilliance of a polished proof die. Strike quality on most 1948 Philadelphia coins is average to strong, with full torch details and crisp letters across the legends. The Full Bands (FB) designation, applied by PCGS and NGC to coins showing fully separated horizontal lines on the torch's central band, is the central condition-rarity overlay on silver-era Roosevelt dimes; the 1948 Philadelphia delivers FB at a rate roughly comparable to its 1947 and 1949 counterparts in the same series.

The 1948 is classified Regular in the Roosevelt series. PCGS and NGC populations are healthy across all grades through MS-66 thanks to widespread roll-saving from original release, and prices through circulated grades track silver melt with a modest numismatic premium. MS-67 Full Bands becomes a meaningful step-up for registry-set builders, and MS-68 FB is the realistic ceiling for most collectors working through the year-by-year date run.
