1950 Proof

The 1950 proof Roosevelt dime is the first proof of the design and the date that the United States Mint resumed proof coinage after an eight-year suspension. Proof production had ended at Philadelphia in 1942 as part of wartime conservation, and the program returned for the 1950 sales year with a five-coin annual proof set sold by mail order at $2.10. The Mint reported 51,386 1950 proof dimes struck, the lowest figure of the entire Roosevelt proof series and a meaningful step below the 57,500 of 1951 and the 81,980 of 1952. The coin carries John R. Sinnock's standard 1946 design rendered from polished dies on polished planchets, with the FDR portrait and the torch reverse executed at the highest definition the Philadelphia presses produced. The "JS" initials at the truncation of the bust remain in the same medallic position used for circulation work, with definition markedly sharper than the working-die counterpart.

The 1950 proof carries the silver-era specifications: 2.5 grams, 17.9 mm diameter, 90% silver and 10% copper, with a reeded edge struck from a collar. Authentication of a 1950 proof focuses on distinguishing genuine proof characteristics from prooflike business strikes that occasionally surface from early-die-state Philadelphia presses. A true proof shows squared, sharply defined rims with a small step where the rim meets the field, fully mirrored fields with consistent reflectivity at every viewing angle, and crisp design details with no softness in the torch flame, leaf veins, or letters. Die-polish lines visible under a 10x loupe sit on the field surface rather than crossing devices; radial flow lines that fan outward from the center indicate a prooflike business strike rather than a true proof. Cameo contrast between frosted devices and mirrored fields was present on the earliest 1950 strikes from freshly prepared dies and is reserved by PCGS and NGC for the CAM designation and the stronger DCAM tier.

Survivor distribution on the 1950 proof spans PR60 through PR67, with PR64 and PR65 the most heavily certified grades. The 51,386 figure makes the 1950 the scarcest date in the postwar Roosevelt proof series, and the date carries a meaningful premium over the later 1951-1955 proofs at every grade tier. Cameo and Deep Cameo populations are scarce, with DCAM examples commanding sharp step-ups. Hairlines from old wipes and contact marks from set storage are the common impairments.
