1992-S Proof

The 1992-S proof Washington quarter was struck at San Francisco to a recorded mintage of 2,858,981 pieces, a figure on the high side of the late clad-proof run and consistent with the early 1990s rebound in proof set demand after the soft late-1980s stretch. The S mintmark sits to the right of Washington's hair queue on the obverse, in the position the mint adopted when mintmarks returned to the obverse in 1968. This issue is the standard Clad Proof, with the cupronickel composition that defined circulation production after 1965: 75 percent copper and 25 percent nickel bonded to a pure-copper core, weighing 5.67 grams. The companion Silver Proof issued in the same year carries the same date and S mintmark but reverts to 90 percent silver at 6.25 grams, sold in a separate premium set, and the two should not be confused at point of sale.

Authentication on this issue runs through the brilliant proof finish first: deeply mirrored fields, crisp square-edged devices, and the squared rim that separates a proof from a circulation strike. The weight test is the cleanest separator from the Silver Proof companion, since the clad piece registers 5.67 grams against the silver piece's 6.25, and edge inspection confirms the reading because the clad coin shows the reddish copper-core line along the rim while the silver coin shows uniform color through the edge profile. By 1992 the Mint's frosted-die preparation routinely produced Deep Cameo, the heaviest contrast designation between mirrored fields and frosted devices, on a substantial share of the run, so PR69 and PR70 Deep Cameo specimens are achievable rather than aspirational. Certification through PCGS, the Professional Coin Grading Service, or NGC, the Numismatic Guaranty Company, settles any question about finish or composition.

In the modern collecting landscape, the 1992-S Clad Proof functions as a routine entry in the late Flanagan-eagle proof run, with most surviving examples sitting at PR68 through PR70 in Deep Cameo. Buyers fall into year-set builders pulling the 1968-onward proof run together, registry collectors chasing PR70 Deep Cameo top-pops, and clad-proof specialists working the final pre-State-Quarter years. Acquisition is straightforward through any major auction house or proof-set dealer, with prices remaining modest until PR70 Deep Cameo, where condition rarity drives the premium.
