1829 Large 10C

The 1829 Large 10C Capped Bust Dime is one of four reverse-denomination size variants produced from the same year, distinguished by the punches the Mint used to strike the digits and letter "C" on the reverse. Engravers worked through Small, Medium, Large, and Extra Large 10C punches as they cut and replaced reverse dies during the year, and the Large 10C lands as the second-largest of the four. Its digits and letter run roughly fifteen to twenty percent taller than the Medium 10C found on the same date, a difference visible under magnification once a collector knows where to look. The combined 1829 mintage of 770,000 pieces was split across these reverse-size groups and across multiple JR die marriages, the shorthand numismatists use for John Reich obverse-and-reverse pairings catalogued in the standard Capped Bust dime reference. The Large 10C is more common than the headline-grabbing Extra Large 10C but scarcer than the Medium 10C that most type collectors encounter first, placing it in a middle tier of demand that rewards patient hunting through auction archives and dealer inventory rather than waiting on a major sale.

Authenticating an 1829 Large 10C begins at the reverse, where the size of the denomination punch is the controlling diagnostic and a caliper or high-resolution photograph is far more reliable than the naked eye. Collectors should measure the height of the "1" in "10" and the "C" against published references for each of the four 1829 size groups, since misattribution between Medium and Large is the most common error in raw-coin listings. Weight should sit at 2.7 grams on a calibrated scale, and diameter at 18.5 millimeters, matching the small-type Capped Bust dime standard introduced for the 1828-1837 portion of the series. Cast counterfeits, occasionally encountered for early dimes, betray themselves through a grainy or pebbled surface texture, soft denticles around the rim, and a dull metallic ring when tipped against a hard surface. For high-grade or expensive examples, a holder from a major third-party grading service, abbreviated TPG and including firms such as PCGS or NGC, provides both authentication and a variety attribution that removes ambiguity from the size punch question. Mint State pieces, where MS denotes the uncirculated grading band from 60 through 70, are genuinely scarce for the Large 10C and trade at strong premiums when properly attributed.

Survival across all grades is estimated in the low thousands, with most known examples falling in the Fine to Extremely Fine range and lustrous originals comparatively few. For collectors building a reverse-size variety set or simply seeking a representative example of the 1829 dime that is neither the easiest nor the toughest of its date, the Large 10C offers a satisfying middle path.
