1952 Proof

The 1952 proof Roosevelt dime is the third proof of the design, struck at Philadelphia in a mintage of 81,980 coins. Annual proof set sales had resumed in 1950 after the wartime suspension, and 1952 marked the third year of the renewed program with collector demand building meaningfully over the inaugural 51,386 and second-year 57,500 figures. The five-coin proof set sold by mail order at $2.10 carried the dime in John R. Sinnock's standard 1946 design, rendered from polished dies on polished planchets. 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 obverse reads FDR with IN GOD WE TRUST and LIBERTY, and the reverse pairs the vertical torch with an olive branch and an oak branch.

The 1952 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 1952 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 fanning 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 early 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 1952 proof spans PR60 through PR67, with PR64 and PR65 the most heavily certified grades. The 81,980 mintage is roughly 60% higher than the 1951 figure and meaningfully eases the supply pressure that drives premiums on the 1950 and 1951 proofs, although the 1952 proof still trades at a step-up over the 1953-1955 issues. Cameo populations are moderate 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. For broader context, see the Roosevelt Dime series history.
