1960-D

The 1960-D quarter came off the Denver presses at 63,000,324 pieces, more than double the Philadelphia output of 30,855,602 and continuing the early-1960s pattern of Denver supplying the larger share of silver-quarter production. The composition stays at 90% silver and 10% copper, a 6.25-gram blank yielding .1808 ounces of actual silver weight, and the D mintmark sits on the reverse below the wreath in this era. That reverse-mintmark placement runs through 1964 before the 1965 to 1967 mintmark suspension and the 1968 move to the obverse, so a 1960-D with the mintmark anywhere except the reverse is by definition not legitimate.

Strike quality on the 1960-D runs from average to good, with the typical era softness on the eagle's breast feathers and on Washington's hair above the ear. The D mintmark itself is the standard authentication checkpoint; examine the punch under five-to-ten-power magnification for any sign of an underlying letter ghost, particularly given that the 1950-D D/S over-mintmark from earlier in the decade established a known precedent for die-shop irregularities on Denver quarters. Bag-marks are the everyday grader's complaint, since the Mint State pool survives primarily through original-roll preservation rather than purposeful collector inclusion. Population reports at PCGS, the Professional Coin Grading Service, show the date plentiful through MS65, with the meaningful drop arriving at MS66 and genuine scarcity at MS67 where registry-set demand sustains four-figure prices.

The 1960-D is a common date in the modern catalog, set-fillable in circulated grades at small premiums over silver melt and obtainable in MS65 without much hunting. Toning enthusiasts seek out the relatively few examples that escaped the dipping cycle of the 1960s and 1970s, since original-skin Denver quarters of this vintage trade at strong premiums when the color is pleasing rather than spotty. Realistic acquisition is a certified MS65 or MS66 from a major auction, with the genuinely difficult upgrade target sitting at MS67 where examples thin sharply enough to draw four-figure money.
