1880

Philadelphia struck 36,000 dimes in 1880, the second year of the four-year low-mintage Philadelphia stretch that ran from 1879 through 1882. The coin is a Legend, No Arrows issue under the 2.50-gram weight standard set by the Coinage Act of February 12, 1873. The 36,000-piece figure is roughly 2.5 times the 1879 delivery and well under any other Seated dime mintage outside the 1879-to-1882 cluster, the 1882 figure that followed, and the small CC issues of the early branch run. Commercial dime demand had collapsed in the wake of the Bland-Allison Act of February 28, 1878, which routed silver capacity into the Morgan dollar program, and Philadelphia was effectively running a token annual dime delivery for collector and bank-vault use rather than for general circulation needs.

Survival follows the same collector-saved pattern as 1879 and the subsequent low-mintage years. Contemporary collectors recognized the small delivery, set aside Mint State examples in deliberate quantity, and that institutional and individual saving has dominated the certified population for over a century. PCGS, the Professional Coin Grading Service, and NGC, the Numismatic Guaranty Company, populations show concentrated Mint State numbers with usable gem MS-65 and even MS-66 representation for a date that on raw mintage alone should read as a rarity at every grade. Circulated examples are genuinely scarce in Very Fine through Extremely Fine, and the date is one of the issues where a problem-free worn coin can run more expensive than a low-end Mint State example, inverting the typical Seated dime pricing curve. Strike quality on Mint State pieces runs sharp, with full shield rivets and crisp wreath detail typical of the small, carefully-supervised die runs used on these limited deliveries. Authentication starts at the 2.50-gram weight, the 17.9-millimeter reeded edge, and date numeral verification against documented references; counterfeit risk is low for an issue of this collector-saved profile.

For collectors, the 1880 is a Semi-Key date with availability concentrated at the top of the grade ladder rather than spread evenly across grades. Buying advice runs the same direction as 1879: well-struck certified Mint State pieces are routinely available and reasonably priced for the mintage, while a problem-free circulated example for a working-grade set requires patience.
