1886 Proof

The 1886 Seated Liberty Dime proof was struck in 886 pieces at Philadelphia, a slight step down from the 930-piece figure of 1884 and 1885 and the lowest delivery to that point in the late-series proof program. Circulation output the same year totaled 6,376,684 dimes from Philadelphia alongside a 206,524 San Francisco issue, the latter classified as a Key Date on the site for its condition rarity in upper grades. The proof issue and the two circulation strikes traced separate paths through the Mint that year: subscription proofs went out to collectors through the Mint Cabinet's order book in small monthly tranches, while the bulk Philadelphia run met active commercial demand and the San Francisco delivery filled trans-Mississippi circulation needs. The 1886 proof shows the Legend obverse with United States of America curving above Liberty's seated figure and the wreath reverse, both rooted in Christian Gobrecht's 1837 design and carried through the late series under Charles E. Barber's engraving administration.

Authentication relies on the standard late-series diagnostics. A genuine 1886 proof shows fully squared rims rising perpendicular to the field, the product of multiple medal-press blows; field structure reads as watery and mirror-deep under a 10x loupe (a jeweler's magnifier), with controlled die-polish lines and no radial flow lines from the design. Denticles, the tooth-like beads at the rim's edge, appear sharp and complete on both sides. Cameo (frosted devices against mirrored fields) and Deep Cameo designations are awarded by PCGS, the Professional Coin Grading Service, and NGC, the Numismatic Guaranty Company, on a portion of the population, with the share running smaller for 1886 than for the early-1880s dates because mid-decade die preparation produced less aggressive device frosting. Specifications must hold at 2.50 grams, 17.9 millimeters, .900 silver with a reeded edge. Because the 1886 Philadelphia business-strike issue can present with prooflike surfaces from early die state, rim and field structure rather than reflectivity carries the burden of identification.

For collectors, the 1886 proof is meaningfully scarcer than the 1880-1885 cluster but more available than the sub-800 deliveries that close out the series. Population data shows a few hundred certified survivors across grades, with PR62 through PR64 the most populated band and gem PR65 and finer pieces scarce relative to demand. Cameo and Deep Cameo cohorts are smaller than for early-1880s dates, which constrains the supply of visually striking examples. Pricing follows the broader late-series proof market and trades on grade and cameo designation rather than the specific 886-piece mintage. The Regular classification on this page follows site convention for proof entries; rarity context is carried in the prose, not the badge. Counterfeit risk is low; 19th-century proof finish work has never been replicated convincingly by counterfeiters.
