1948-D

The 1948-D Roosevelt dime is the third Denver strike of John R. Sinnock's design, with 52,841,000 pieces produced as the Mint settled into normalized postwar output. Denver's 52,841,000 figure runs closer to Philadelphia's 74,950,000 than the silver-era norm; the Mint kept the two facility totals within a tighter ratio in 1948 as Mountain States retail expanded and the West Coast San Francisco facility absorbed a heavier share of regional circulation needs. The "D" mintmark sits on the reverse to the left of the torch base, the branch-mint placement Sinnock had engraved into the master dies before the series went to press. 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. Sinnock had died in May 1947, so the 1948-D is the first full year of dime production after his tenure, struck from working dies sunk from his original master hub.

The 1948-D 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 Denver strike begins with the weight check at roughly 2.45 to 2.55 grams in any reasonably preserved example. The "D" mintmark should be cleanly punched without remnant of another letter beneath it, the standard diagnostic check across silver-era branch-mint Roosevelt dimes. Strike quality at Denver in 1948 is typically strong with crisp torch flame, well-defined leaf veins on the olive and oak branches, and clean letters across the legends; late-die-state examples occasionally show softness in the horizontal band lines on the torch. 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 and matters at MS-65 and higher.

The 1948-D is classified Regular in the Roosevelt series. PCGS and NGC populations are strong across circulated and lower Mint State grades thanks to roll-saving from original release, and Denver coins of the date deliver Full Bands at a high rate through MS-66 FB. MS-67 FB and finer become meaningful condition rarities and the realistic ceiling for registry-set builders working through the date run. For broader context, see the Roosevelt Dime series history.
