Denver delivered 596,810,688 quarters in 1988, once again exceeding Philadelphia's production. The branch mint's consistent edge in output reflected both its efficient press operations and the growing commercial demand in the western states, where population growth outpaced the national average throughout the 1980s.
The 1988-D saw heavy commercial use and is available in all grades. Mint State examples from rolls and mint sets are plentiful. No notable varieties have been documented for the date. The coin fills its slot in a clad-era set at standard pricing, interchangeable in collector terms with its immediate neighbors in the late-1980s sequence.
