Capped Bust Half Dimes (1829–1837)

A Twenty-Four Year Absence and a July Fourth Revival

The half dime vanished from American commerce after 1805 and did not return for twenty-four years. The most plausible explanation offered by numismatic scholars, including Breen, is that banks found the circulating Mexican half-reale, worth one-sixteenth of a dollar and close to the half dime's five-cent value, a perfectly adequate substitute for small change and saw no pressing need to request federal half dimes from the Mint. Whatever the cause, the denomination quietly ceased production after its Draped Bust run ended in 1805, and for nearly a quarter century no new five-cent silver pieces were struck.¹

The revival was ceremonial. On July 4, 1829, as workers prepared to lay the cornerstone of the second Philadelphia Mint building, the Mint struck the first new half dimes early that morning. Proof examples were placed into the cornerstone alongside a 1792 half disme, copies of the Declaration of Independence, the Constitution, and George Washington's Farewell Address. The 1829 Proof half dime survives in a larger population than any other date in the series, its numbers elevated by the occasion's significance and by deliberate production for presentation and collector purposes. Logan and McCloskey attribute confirmed Proofs to four die marriages of the 1829 date.²

Reich's Design, Kneass's Adaptation

The Capped Bust design's intellectual origin belongs to John Reich, a German immigrant who served as assistant engraver at the Mint from 1807 to 1817. Reich introduced the Capped Bust motif on the half dollar in 1807; versions appeared on the dime from 1809 and the quarter from 1815, making it the dominant design language of early nineteenth-century American silver well before the half dime adopted it. Among Reich's lasting contributions was the practice of explicitly marking the denomination on his coin designs, something the Mint had neglected through the Flowing Hair and Draped Bust eras when citizens identified a coin's value by size and weight alone.³

By 1829 Reich had been gone from the Mint for more than a decade. William Kneass, the second Chief Engraver, adapted Reich's design for the new half dime, modifying the portrait sufficiently to receive his own design credit while building clearly on the established Capped Bust family. After Kneass suffered a stroke in 1835 and his physical capabilities became impaired, Christian Gobrecht, who had been preparing letter and numeral punches for the Capped Bust coinage, stepped in to assist with engraving duties. Gobrecht subsequently designed the Seated Liberty series that replaced the Capped Bust on all silver denominations beginning in 1837.⁴

Liberty Faces Left; the Denomination Is Finally Marked

Liberty faces left, reversed from the Draped Bust type's right-facing portrait. Her hair is mostly gathered beneath a cloth cap whose band carries the inscription LIBERTY. Loose tresses fall from under the cap to her shoulder, and her gown, fastened with a brooch at the shoulder, drapes across her neckline. Thirteen six-pointed stars, seven to the left and six to the right, surround the portrait. The date appears below.

The reverse carries a centered eagle with wings partially raised rather than the fully upswept heraldic spread of the Draped Bust type. The Union Shield covers the eagle's breast. E PLURIBUS UNUM appears on a scroll above, UNITED STATES OF AMERICA arcs along the upper three-quarters, and the denomination 5 C. appears at the bottom. That denomination marking is a structural departure from everything that came before in the half dime series: all previous types had relied on size and weight to communicate value. The 5 C. made its value legible to any holder regardless of familiarity with the federal coinage. The diameter shrank slightly from the Draped Bust type's 16.5 millimeters to 15.5 millimeters; silver content and weight remained 89.24 percent silver at 1.34 grams.⁵

The Close Collar and What It Changed

The Capped Bust half dime was struck using close collar technology, a significant mechanical advance the Mint had adopted in the late 1820s. Earlier coins had their edges processed separately before striking: the planchet ran through a Castaing machine to impress edge reeding, then was struck between the obverse and reverse dies. The close collar eliminated this separate step by incorporating an edge die that surrounded the coin during striking, imparting the reeded edge simultaneously with the obverse and reverse impressions.⁶

The consequences for coin quality were substantial. Metal that previously spread outward from striking pressure was now constrained by the collar and forced to flow into the design details instead, producing sharper relief and more complete impressions in Liberty's hair and the eagle's features. The collar also ensured uniform diameter, eliminating the irregular edges of earlier American silver. It enabled properly mirrored Proof surfaces, since the sharply struck fields of a close-collar coin could be polished to a genuine mirror finish in a way that earlier issues could not. Capped Bust half dimes are significantly better struck, more consistent, and more available in higher grades than any of their predecessors in the denomination.

Production and Varieties

Half dime production from 1829 through 1837 was solid and largely uninterrupted. Annual mintages exceeded one million in seven of the nine years, falling below that threshold only in 1832 (965,000) and 1837 (871,000). The peak came in 1835 at 2,760,000 pieces, the highest annual production in the denomination's history to that point. Total series production reached 13,058,700 pieces. The series contains no date rarities in the conventional sense; every date is available in circulated grades at moderate prices, and a complete nine-date set in Very Fine can be assembled for roughly the cost of a single common-date early American silver coin in comparable condition.

Where the series rewards the specialist is in die varieties. Logan and McCloskey catalogued 92 die marriages in Federal Half Dimes 1792–1837, with most dates showing multiple pairings. The varieties arise primarily from different letter and numeral punches used for the legends and denominations, producing the date and denomination size combinations that are the series' most collected distinctions. The 1835 date offers four major combinations: Large Date with Large 5C, Large Date with Small 5C, Small Date with Large 5C, and Small Date with Small 5C. The 1836 carries Large 5C and Small 5C variants. The 1837 similarly presents both denomination size designations.⁷

The 1834 carries an inverted-3 variety, where the digit 3 in the date was punched backwards into the die and then corrected by overpunching it right-side-up. The error remains visible under low magnification and represents one of the more unusual die preparation blunders in early American coinage. Only two die marriages across the entire series rise to the level of genuine rarity: the 1833 LM-5 and the 1835 LM-12, both scarce enough to challenge well-resourced variety collectors.

The 1829 Has the Largest Proof Population; All Others Are Rare

Proof half dimes are known for various dates across the series. The 1829 has the largest confirmed population, a consequence of the July 4 cornerstone ceremony and deliberate presentation striking. The 1831 also shows a relatively high Proof population, attributed to apparently deliberate production that year. Other dates have very small Proof populations, some years represented by only a handful of confirmed examples. All Proof Capped Bust half dimes are expensive in any grade; those with Cameo or Deep Cameo designations command additional premiums. Distinguishing genuine Proofs from high-quality business strikes from fresh dies requires careful examination even with close collar coins, where the generally sharp strikes narrow the visual gap between the two categories.⁸

Building the Set

The Capped Bust half dime occupies a distinctive position in early American silver collecting: historically significant, connected to a major Mint technological transition, yet accessible enough that a serious collector can build a complete date set without encountering anything approaching the 1802 Draped Bust obstacle. Very Good through Very Fine examples of all nine dates are regularly available. Extremely Fine and About Uncirculated coins can be found with reasonable searching. Gems (Mint State 65 or finer) are elusive; Superb Gems are rare enough that individual examples draw competitive auction attention.

For the type collector, a single example in any grade from Good through Gem completes this entry in the half dime series, and the abundant supply of common-date coins in Very Fine makes that an affordable goal. For the date collector, the 1837 presents the most challenge in ordinary circulated grades due to its below-average mintage. For the variety specialist, Logan and McCloskey's 92 die marriages provide a structured collecting framework that most specialist sources consider achievable with patience; the full set has been estimated at under $20,000 in total, with most die marriages found unattributed in dealer stock at common-date prices. Only the 1833 LM-5, 1835 LM-12, and 1837 Small 5C require deliberate searching and meaningful budget.
