1830 Proof

An early Small Type proof from the Philadelphia coinage program, the 1830 Capped Bust dime is one of the rarest presentation strikings of the John Reich design and carries an R.7 rarity rating, meaning only four to twelve examples are believed to exist across all grades. Proof production in this era was not a formal commercial program. Mint workers prepared a handful of carefully polished planchets, struck them on freshly burnished dies, and reserved the pieces for visiting dignitaries, cabinet specimens, or favored collectors who requested examples directly from Philadelphia. No mintage figure was ever recorded because these strikings were treated as one-off courtesies rather than catalogued production, and the 510,000 figure shown elsewhere on this page reflects the combined business-strike total for the year rather than the proof issue. Recent auction appearances at the major firms have placed certified survivors in the mid-to-high five-figure range, with finer examples occasionally crossing into six figures when provenance traces back to a named nineteenth-century cabinet.

Authentication of an 1830 proof Capped Bust dime hinges on a small group of physical traits that genuine pieces share and that altered business strikes cannot fully replicate. The fields should display a true watery mirror reflectivity rather than the brushed shimmer of a polished circulation coin, and the rims must appear squared and crisp where die pressure from a slow, deliberate strike forced metal fully into the collar. Cameo frost, when present, sits on the highest devices including the curls of Liberty and the eagle's breast feathers, contrasting sharply against the reflective background. Weight should fall at 2.7 grams and diameter at 18.5 millimeters consistent with the Small Type specification adopted in 1828. Any deviation in weight beyond a few hundredths of a gram, or any softness at the dentils, points to a circulated business strike that has been polished to mimic a proof. Because counterfeits and altered pieces appear regularly, no example should be acquired without certification by a major third-party grading service that has designated the coin as Proof, abbreviated PR on the holder label.

For collectors building a type set of early federal silver, the 1830 proof represents one of the toughest acquisition targets in the entire Capped Bust dime run, and opportunities to purchase a certified example often arrive only once or twice per decade at public sale.
