1988-P

The 1988-P is the first Roosevelt dime struck above one billion pieces at a single facility since the no-mintmark 1967 output reached 2.24 billion under the 1965-1967 mintmark suspension. Philadelphia delivered 1,030,550,000 dimes in 1988, the first billion-coin year for the mintmarked Roosevelt series and a benchmark that defines the date within the broader Roosevelt arc. The figure tracked sustained late-decade coin demand and reflected Philadelphia's gradual rebuild of production capacity through the 1980s. The P 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 across the year held to the better-than-average late-1980s standard.

Authentication runs the standard clad-dime checklist: 2.268 grams on a calibrated scale, P 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 recoverable on 1988-P at reasonable rates from original Mint sets and bank-wrapped rolls. Strike quality runs slightly above the surrounding years and FB premiums concentrate at MS67 FB and finer where population reports thin enough to support a real condition-rarity tier. No major business-strike die varieties carry Cherrypickers attribution at the principal level, and the date carries no recognized RPM or doubled-die premium varieties.

The 1988-P trades at flat type-coin levels through MS66 and steps up at MS67 FB where the PCGS and NGC population data thin to registry-relevant numbers. MS68 FB examples reach the four-figure range at public auction when certified by a major service. The billion-coin distinction gives the date a useful narrative hook for year-set and date-set builders even though it carries no scarcity premium at common grades; the date is sometimes pulled aside as a first-year-of-billion marker in display sets alongside the same year's nickel and cent production figures. Original Mint sets and bank-wrapped rolls remain the practical hunting ground for upgrade-grade examples.
