William Kneass designed the Capped Bust half dime, though the degree to which he borrowed from John Reich's earlier work is hard to ignore. Reich had created the Capped Bust motif for the half dollar in 1807, and when the half dime returned to production in 1829 after a twenty-three-year absence, Kneass essentially adapted Reich's portrait to the smaller format. Liberty faced left wearing a cloth cap with the word LIBERTY on the band, her hair curling below, surrounded by stars and the date. The reverse carried an eagle with a shield on its breast, arrows and olive branch in its talons, and the inscription UNITED STATES OF AMERICA around the border. It was a handsome enough design, well suited to the coin's small diameter, and it gave the half dime a visual consistency with the other silver denominations that had been using versions of the Capped Bust motif for years. Kneass had succeeded Robert Scot as Chief Engraver in 1824, and while he was a competent engraver, his health was poor. He suffered a debilitating stroke in 1835, after which most of the Mint's die work fell to Christian Gobrecht and other assistants.
The half dime's return in 1829 came about because the Mint finally had both the capacity and the economic incentive to produce small silver coins again. The long gap from 1805 to 1829 had left Americans dependent on Spanish and Mexican silver fractions for small transactions, a situation that Congress and the Mint found embarrassing but had been unable to remedy during a period when full-weight silver coins were worth more melted than spent. By the late 1820s, conditions had shifted enough to make the half dime viable again, and production began at a respectable clip. The Mint struck over 1.2 million half dimes in 1829, a quantity that dwarfed the entire Draped Bust half dime output of all years combined.
The series ran from 1829 through 1837, just nine years, and is conventionally divided into two subtypes based on a technical change in the striking process. The earlier coins, 1829 through 1835 or so, were struck without a restraining collar and have a slightly irregular edge. Beginning around 1835 and continuing through 1837, the Mint adopted a close collar that produced a more uniform edge and a more precisely round coin. The transition was gradual rather than instantaneous, and the exact dividing line depends on which die varieties you are looking at. The close-collar coins have a slightly different look, sharper and more mechanical, that collectors can learn to recognize with a little practice.
Production was steady throughout the run. Annual mintages ranged from about 871,000 in 1837 up to 2.76 million in 1835, respectable numbers that kept the coins in circulation and visible in everyday commerce. There were no years skipped and no dramatic production drops. The Mint had figured out how to make half dimes efficiently, and it did so without interruption until the design was replaced.
The Capped Bust half dime ended in 1837 when the Mint transitioned to Christian Gobrecht's Seated Liberty design, part of a broader redesign of the silver coinage that had begun with the Gobrecht dollar in 1836. Kneass was incapacitated by that point, and Gobrecht was running the engraving department in all but title. The changeover happened midyear, and both Capped Bust and Seated Liberty half dimes carry the 1837 date, making it a transitional year for collectors. The Capped Bust version of 1837 is the scarcer of the two types for that date, as production shifted to the new design relatively early in the year.
The Capped Bust half dime series has no dramatic rarities. The mintages are consistent enough that no single date stands far apart from the others. The 1837 Capped Bust, with its lower share of that year's production, is probably the toughest date to find in higher grades, but it is not rare in any absolute sense. The 1829 coins are popular as the first half dimes in over two decades, and they were saved in somewhat larger numbers than surrounding dates, which means they turn up in better condition more often than you might expect. Logan and McCloskey catalogued the die varieties for the series, and while the number of recognized die marriages is smaller than for the Capped Bust half dollars, there is enough variety to keep a specialist engaged. Several dates show overdates or repunched features, with the 1830 and 1835 offering minor but collectible varieties. Large Date and Small Date variants exist for some years, adding a layer of complexity that the short series length might not suggest at first glance.
Proofs exist for most if not all dates in the series, though they were struck in very small numbers, typically a few dozen to perhaps a hundred pieces per year. Many of these ended up in presentation sets given to foreign dignitaries or sold to the small community of coin collectors that existed in the early nineteenth century. Surviving proofs are scarce across the board and seldom appear at auction.
Five cents in the 1830s still bought something tangible. A newspaper, a couple of eggs, a measure of milk, a short omnibus ride in the larger cities. The half dime had returned to a marketplace that had managed without it for over twenty years by relying on foreign silver, and the coin had to reestablish itself. It did so fairly quickly, helped by mintages large enough to actually make a difference in circulation. By the mid-1830s, the half dime was a familiar coin in everyday commerce along the eastern seaboard, used in shops, markets, and taverns for the small purchases that copper cents were too bulky to handle conveniently and dimes were too valuable to waste on. The coins circulated alongside the same Spanish and Mexican fractions they were supposed to replace, and the foreign silver did not disappear overnight, but the gap was closing. The Capped Bust half dime was a transitional coin in more ways than one. It bridged the long production gap between the early republic's sporadic silver output and the more industrialized coinage of the Seated Liberty era, and it proved that the Mint could sustain production of the denomination at volumes that actually served the economy. That may not sound like much, but after twenty-three years with no half dimes at all, it was progress.
