1988-D

Denver delivered 962,385,489 Roosevelt dimes in 1988, narrowly missing the billion-coin mark that Philadelphia reached the same year and producing the highest Denver dime output up to that point in the series. The figure tracked the same late-decade Federal Reserve demand that pushed Philadelphia past one billion and reflected Denver's expanded capacity following the equipment upgrades carried out earlier in the 1980s. The D mintmark sat above the date in its established position, the clad sandwich kept the 2.268-gram, 17.91-millimeter cupronickel-on-pure-copper specification, and strike quality came up to the cleaner late-1980s Denver standard. As a year, 1988 is the closest matched-pair Philadelphia-Denver high-production figure in the modern Roosevelt run.

Authentication on the 1988-D follows the standard clad-dime checklist: 2.268 grams on a calibrated scale, D mintmark sharp above the date under 10x magnification, and Full Bands evaluation across the central torch. Full Bands, the third-party grading designation that the two parallel horizontal bands at the torch midpoint show complete separation, is reasonably available on 1988-D because the year's Denver strike quality is solid and dies stayed within useful service life on most working presses. The FB premium concentrates at MS67 FB and finer where PCGS and NGC population reports thin enough to support registry-grade competition. No major business-strike die varieties carry Cherrypickers attribution at the principal level.

The 1988-D survives in heavy quantity through MS66 and trades at standard type-coin pricing at and below that grade. The condition-rarity tier opens at MS67 FB where population reports thin to registry-relevant levels; MS68 FB examples step into the four-figure range at public auction when certified by a major service. Pairing the 1988-D with the 1988-P gives collectors the meaningful matched-mint near-billion-coin marker of the decade, and the two issues sit together in display sets that highlight the 1988 production milestone. Original Mint sets and bank-wrapped rolls remain the practical hunting ground for upgrade-grade material, and base-grade pricing has held flat for decades. The 1988-D shows no fundamental scarcity at common grades and remains a routine entry in modern Roosevelt date sets.
