1956

The 1956 Washington quarter came from the Philadelphia Mint at 44,813,384 pieces, a strong recovery from the smaller 1955 output and reflecting renewed quarter demand mid-decade. No mintmark appears on the obverse or reverse, since Philadelphia did not begin using a P mark on quarters until 1980. Denver carried the only other 1956 quarter production at 32.3 million pieces; San Francisco had ended business-strike quarter production after 1954-S and would not resume until well after the 1965 mintmark suspension ended. That two-mint configuration becomes the norm from 1956 through 1964 for silver-era Washington quarters, with Philadelphia and Denver splitting the entire output.

Strike quality on 1956 Philadelphia coins comes generally well executed, with sharper hair detail and crisper eagle plumage than the contemporary Denver issue. Gem examples through MS66 with full devices and original satin luster are obtainable, and the population thins gradually at MS67. Bag-marks rather than strike weakness drive most graded coins down a point at the upper end of the curve, since the surviving Mint State examples mostly entered the market through original BU roll preservation. No major doubled-die or repunched-mintmark varieties are recognized for 1956 by PCGS, the Professional Coin Grading Service, or NGC, the Numismatic Guaranty Company. Counterfeit concerns are minimal at face-silver values, and any 1956 quarter showing a mintmark of any kind would identify itself as either a Denver issue or a fake.

In market terms, 1956 classifies as a Regular date and trades at common-date silver levels through about MS65. The collecting interest sits at MS66 and above, where condition-rare examples command real premiums from registry-set collectors targeting full strikes. A date-set builder fills this slot inexpensively at any circulated grade, and the date offers no specific authentication concern. Roll-hunting still occasionally rewards searchers, since original BU rolls of 1956-P appear regularly in dealer inventories and estate liquidations; cherry-picking can yield clean MS66 candidates from typical bag-mark-affected rolls if the searcher knows the Philadelphia strike profile.
