1988-P

The 1988-P quarter was struck to 562,052,000 pieces, a routine Philadelphia mintage for the late 1980s and just below the Denver counterpart of the same year. The P mintmark sits at the right side of Washington's hair queue on the obverse, in the position established when Philadelphia first applied a mintmark to the denomination in 1980. The coin is a standard 75% copper over 25% nickel clad strike bonded to a pure-copper core, weighing 5.67 grams against the 6.25 grams of pre-1965 silver Washingtons, with the reddish copper edge line the immediate visual confirmation of clad composition. Nothing about the design, composition, or production routine for the date breaks from the established late-1980s pattern of high-volume Philadelphia output.

Strike quality on the issue is generally good. Philadelphia presses in 1988 produced reliable obverse detail and adequate reverse fill, with the eagle's breast feathers and arrow definition at center reverse the routine soft spots when planchet fill came up short. Look for full step lines in the eagle's tail and crisp arrow points below the bird as the standard markers of a fully struck example; a mushy center reverse on an otherwise lustrous coin signals incomplete fill under die pressure rather than a worn coin. No major doubled-die obverses or repunched-mintmark varieties have been formally attributed to the date by PCGS, the Professional Coin Grading Service, or NGC, the Numismatic Guaranty Company, so cherrypicking yields are thin. Counterfeit pressure is essentially absent because the coin trades at face value through MS64.

In collecting terms, the 1988-P is a common date and the site classifies it Regular. MS65 and MS66 examples are routine and inexpensive, with 1988 mint sets and original bank-wrapped rolls providing the practical supply pool for higher-grade material. Condition rarity arrives at MS67 and above, where strike softness, minor planchet flaws, and bag-mark accumulation thin the certified population sharply, and registry-set collectors pay meaningful premiums for the few luster-bright Gems with full central detail. A year-set builder fills the slot at minimal cost; an upgrade-path collector pursues certified MS67 examples from fresh mint-set submissions rather than the dealer secondary market.
