1971-S Proof

The 1971-S proof Washington quarter was struck at San Francisco to a recorded mintage of 3,220,733 pieces, a strong rebound from 1970-S's 2,632,810 figure and a return to the three-million range that would hold through the rest of the early clad-proof run. The increase tracked renewed proof set demand as collectors absorbed the new Eisenhower dollar denomination, which made its proof debut in 1971-S clad sets and lifted overall proof set sales across all five proof denominations. 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 through the early 1970s, occasionally producing minor positional differences across the run, with no major catalogued mintmark varieties for the 1971-S quarter specifically. Cameo, the strong contrast between mirrored fields and frosted devices, occurs on a meaningful and growing share of dies as Mint die preparation continued refining frosting practice, and Deep Cameo specimens at Proof 67 and above appear regularly in graded inventory. Counterfeits of early-1970s clad proofs do not meaningfully exist because the coin returns nothing against production cost. 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 1971-S proof is a common date in the early clad-proof run, with raw and certified supply readily available through Proof 67 and modest premiums emerging at Proof 68. The price profile widens at the Cameo and Deep Cameo level, where Deep Cameo Proof 69 examples remain a credible registry target. Buyers cluster into year-set builders working the modern clad-proof run, registry collectors chasing top-pop Deep Cameo strikes, parent-set buyers acquiring the quarter alongside the first-year Eisenhower dollar proof, and Washington specialists.
