1958-D

The 1958-D quarter came off the Denver presses at 78,124,900 pieces, dwarfing the Philadelphia output of 6,360,000 by more than twelve to one and confirming Denver's role as the primary quarter mint during the late 1950s. The Philadelphia and Denver split that year was the most lopsided of the entire silver run, a Treasury allocation that reflected regional cash flow rather than any production constraint. 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.

Strike quality on the 1958-D runs from average to good, with the eagle's breast feathers and Washington's hair above the ear the first details to soften on weakly struck examples. The mintmark punch itself is the standard authentication check; examine the D under five-to-ten-power magnification for any underlying letter ghost, since the 1950-D D/S over-mintmark variety from earlier in the decade originated in the same die-shop practice and the era's craftsmen made similar errors on adjacent dates. Counterfeit risk on the standard date is minimal at face-silver values. Population reports at PCGS, the Professional Coin Grading Service, show the issue well-represented through MS65, with a noticeable thinning at MS66 and genuine scarcity above that mark; toned examples with original skin command premiums over dipped pieces, since most surviving coins passed through the dipping cycle of the 1960s and 1970s.

The 1958-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. Roll-hunters and year-set builders make up most of the buyer base, with registry collectors focused on the high-Mint-State pool where the issue thins. Realistic acquisition is a certified MS65 or MS66 from a major auction, with the genuinely scarce upgrade target sitting at MS67 where the population drops sharply.
