1991-D

The 1991-D quarter posted 630,966,693 pieces, well off the 927-million peak of 1990-D and back into the more typical Denver range for the era. That step down is the date's most distinctive structural fact in context: Denver's two-year surge of 1989-1990 ended with 1991, though production stayed comfortably above 600 million and well above the sharply reduced 1992-D figure that followed. The D mintmark sits at the right side of Washington's hair queue on the obverse, in the position established when mintmarks moved off the reverse in 1968. The coin is a standard 75% copper over 25% nickel clad strike weighing 5.67 grams, with the reddish copper edge line the immediate visual confirmation of clad composition rather than a pre-1965 silver hold-over.

Strike quality on the date is uneven. Denver presses in 1991 produced perceptible softness on Washington's hair detail and on the eagle's breast feathers at center reverse, both areas where reduced die pressure on the sandwich planchet left incomplete fill. Look for crisp tail-feather definition and sharp arrow detail below the bird as the standard markers of a full strike; weakness clusters in those zones rather than at the rim. No major doubled-die obverses or repunched-mintmark varieties have been formally attributed to the date by PCGS, the Professional Coin Grading Service, or NGC, the Numismatic Guaranty Company. Counterfeit pressure is essentially absent because the coin trades at face value through circulated grades and no economic motive exists to fake it.

In collecting terms, the 1991-D is a common Regular issue: easy to fill a date set in MS63 through MS65 from any dealer or auction lot, and reasonable at MS66. The condition story tightens at MS67 and above, where typical Denver strike softness combines with bag-mark accumulation to leave the certified population thin enough that registry-set collectors compete meaningfully for full-luster Gems with sharp central detail. Original 1991 mint sets and BU rolls remain the practical hunting ground for upgrade material; modern submissions of bulk-stored coins occasionally produce the kind of luster-bright Gem that grades against the date's middling reputation.
