1974-S Proof

The 1974-S proof Washington quarter was struck at San Francisco to a recorded mintage of 2,612,568 pieces, the lowest figure of the 1968 to 1974 clad-proof stretch and the closing year of the standard pre-Bicentennial reverse design. The 1974-S proof set was the last to carry the heraldic eagle reverse before the dual-dated 1776 to 1976 Bicentennial drum-and-torch reverse by Jack L. Ahr took over for the 1975 and 1976 issues, and no quarter dated 1975 exists, since the 1975-dated Bicentennial proof and circulation strikes were not produced. The coin carries John Flanagan's portrait of Washington on the obverse with the JF initials at the truncation of the neck and the S mintmark to the right of Washington's hair queue. The reverse retains the heraldic eagle. Composition is 75% copper and 25% nickel clad over a pure copper core, at 5.67 grams.

Authentication runs through the brilliant proof finish: deeply mirrored fields, crisp square-edged devices, and the squared rim that separates a proof from a well-struck business strike. A weight test at 5.67 grams distinguishes the clad proof from any 90% silver same-design piece at 6.25 grams. The S mintmark sits on the obverse and was hand-punched into working dies for this year, with no major catalogued mintmark varieties for the date. Cameo, the strong contrast between mirrored fields and frosted devices, occurs on a majority of 1974-S proof dies, and Deep Cameo specimens at Proof 67 and above appear regularly in graded inventory. Proof 69 Deep Cameo strikes are widely available, and the population data thins meaningfully only at Proof 70 Deep Cameo. Certification through PCGS, the Professional Coin Grading Service, or NGC, the Numismatic Guaranty Company, is the working standard for any premium-grade buy.

In today's catalog, the 1974-S proof is the low-mintage anchor of the pre-Bicentennial clad-proof run, with raw and certified supply readily available through Proof 68 and Cameo and Deep Cameo strikes available at modest premiums up to Proof 69. The price profile sharpens at Proof 70 Deep Cameo, where the population thins and registry competition emerges. The date matters structurally as the final eagle-reverse proof before the two-year Bicentennial interruption. Buyers cluster into year-set builders working the modern clad-proof run, registry collectors chasing top-pop Deep Cameo strikes, last-of-type specialists, and Washington completists.
