1968-D

The 1968-D quarter is the first Denver quarter in four years to carry a mintmark, and the first Denver Washington quarter ever to wear its mintmark on the obverse. The Mint struck 101,534,000 pieces at Denver, less than half the Philadelphia 1968 output of 220,731,500 and a reversal of the Denver-leads-Philadelphia pattern that had defined most of the silver-era 1950s and early 1960s. The composition holds at the clad alloy of 75% copper and 25% nickel bonded to a pure copper core, with the finished blank weighing 5.67 grams and containing no silver. The D mintmark sits to the right of Washington's hair queue on the obverse, which is the new and permanent position from 1968 onward and a structural break from the reverse-below-the-wreath placement used 1932 through 1964.

Strike quality on the 1968-D runs from average to good, with the era's typical softness on the eagle's breast feathers and on Washington's hair detail above the ear. The new mintmark position is itself the most important authentication feature on the issue. A 1968-D with the D anywhere except the obverse is by definition not legitimate, and pre-1965 silver Washington quarters carry their mintmark on the reverse below the wreath, so the mintmark position is a quick visual disambiguation between silver-era and clad-era Denver pieces. The mintmark punch deserves the usual five-to-ten-power look for any underlying letter ghost, particularly given the era's punch transitions and the historical precedent of 1950-D D/S over-mintmark errors. Weight and edge tests confirm clad at 5.67 grams with the reddish copper-core edge line. Population reports at PCGS, the Professional Coin Grading Service, show the issue plentiful through MS65, with a clear drop at MS66 and genuine condition rarity at MS67.

The 1968-D is a common date in the modern catalog, set-fillable in circulated grades essentially at face value and obtainable in MS65 without much patience. The date holds collector interest beyond raw rarity because it represents the first obverse-mintmark Denver Washington quarter, a structural waypoint in the series that type-set builders sometimes anchor on. Registry-set builders chase the thin MS67 pool. Realistic acquisition is a certified MS65 or MS66 from a major auction, with the upgrade path running into resistance at MS67.
