1950-D Washington Quarter

The 1950-D quarter is the standard Denver issue for the year, with 21,075,600 pieces struck across both the normal die marriage and the small portion that came off the famous D/S over-mintmark dies. The combined total is the reported figure; collectors and grading services treat the over-mintmark as a separate variety catalog entry, leaving the standard 1950-D as the routine Denver run. The 1950 Denver and San Francisco production is most famous for those over-mintmark errors, where the die shop punched a D over an underlying S on Denver dies and an S over an underlying D on San Francisco dies. The standard 1950-D discussed here is the normal-die companion, with a clean D mintmark on the reverse below the wreath.

Strike on the standard 1950-D is generally crisp, with Denver's mid-century die work showing well on the eagle's breast feathers and Washington's hair detail above the ear. The single most important authentication step is mintmark inspection under five-to-ten-power magnification: confirm that the D punch sits cleanly on the field with no underlying S ghost, since any trace of an S below or beside the D moves the coin into the variety catalog at significantly higher value. The standard 1950-D itself is not heavily counterfeited, but added-mintmark alterations of common 1950 Philadelphia coins to mimic the Denver issue do occur, and the diagnostic is tooling around the punch base. Population reports at PCGS, the Professional Coin Grading Service, show the date is well-represented through MS65, with the meaningful condition pressure at MS66 and above.

The standard 1950-D is a common date today, set-fillable in circulated grades for modest premiums over silver melt and obtainable in MS65 without much hunting. Sharp collectors examine every raw 1950-D for the D/S over-mintmark before relegating it to type-coin status, since cherrypicking opportunities for the variety still exist in dealer back stock. Realistic acquisition for the standard issue is a certified MS65 or MS66 from a major auction, with the genuinely difficult upgrade target arriving at MS67 where the population census thins and four-figure pricing applies.
