1974-S Proof

The 1974-S Proof Roosevelt Dime is the standard S-mint proof issue of the year, reported at 2,612,568 sets struck at the San Francisco Assay Office. Proof set demand had softened from the 1972 peak, and the 1974 figure sits below both the 1973 and 1975 totals, though only modestly. The S mintmark appears below the date on the obverse in its standard proof position, with the rest of the design carried forward unchanged from the long-running Sinnock obverse and the torch-and-branches reverse. The 1974 proof program ran without any reported No-S errors in the dime denomination, so the issue is a clean, standard proof year sandwiched between the 1970 and 1975 No-S rarities.

Authentication rests on standard proof diagnostics. Genuine examples show deeply mirrored fields with the proof depth that no business strike from any mint can replicate, squared rim transitions instead of the rounded rims of a circulation coin, and crisp definition across Roosevelt's profile and the reverse torch. The S mintmark must be sharp and well-formed with clean interior loops; weak or partially filled mintmarks are common on heavily worn proof dies and should be examined under magnification before any varietal claim. Cameo (CAM) and Deep Cameo (DCAM) designations are awarded when contrast between frosted devices and mirrored fields is strong, and 1974-S cameo populations sit comfortably within the mid-clad-era range with good access to DCAM material in PR68 and PR69 grades.

For collectors, the 1974-S Proof is common in the proof set itself and the standard target for type collectors filling in the year. PR69 DCAM examples are widely available through broken proof sets, and PR70 DCAM is the genuine condition rarity at the top of the grading scale, where prices climb sharply. The lower proof set mintage relative to the early 1970s has not translated into meaningfully higher PR69 DCAM prices, since cameo survival in original government packaging has been excellent. PR70 DCAM remains the only price tier where the date carries real premium. For broader context on the clad-era proof program, see the Roosevelt Dime series history.
