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 real, 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. One of the new half dimes, probably a Proof, went into the cornerstone with the day's newspapers, copies of the Declaration of Independence, the Constitution, and George Washington's Farewell Address, and other specimen coins including a 1792 half disme. 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 probable production of presentation pieces. 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. Reich's designs carried the denomination on the reverse, which the Mint had done only inconsistently on its earlier silver: the dollar and half dollar carried their value in the edge lettering, the 1804 to 1807 quarter carried 25 C., and the half dime and dime carried none at all.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 the half dime and dime in 1837, the quarter in 1838, and the half dollar in 1839.⁴

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. No earlier half dime had carried its denomination: 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 1.35 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 allowed the Mint to strike Proofs with crisper detail and better polished surfaces. 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 at 2026 retail guide values of roughly $165 to $250 a coin in VF-20, a complete nine-date set in Very Fine costs about $1,500.

Where the series rewards the specialist is in die varieties. Logan and McCloskey catalogued 91 die marriages in Federal Half Dimes 1792–1837, with most dates showing multiple pairings. The best-known varieties arise from different numeral and letter punches used for the dates 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 a 3 Over Inverted 3 variety, where the digit 3 in the date was first punched upside down into the die and then corrected by overpunching it right-side-up. The error remains visible under low magnification, and the same 3 Over Inverted 3 blunder recurs on the 1836 half dime. The two great rarities among the die marriages are the 1833 LM-5 and the 1835 LM-12, each rated Rarity-7 or rarer and 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 probable presentation striking. The 1834 has the next largest Proof population by PCGS estimates, while Logan and McCloskey regard many coins once called 1831 Proofs as early die states. 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, and the few certified with 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 is historically significant and tied to a major Mint technological transition, yet 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 91 die marriages provide a structured collecting framework; Andrew Kolbert estimated in 2023 that the full set can likely be assembled for under $20,000, with most coins sitting unattributed in dealer stock, though some marriages are challenging to locate.⁸ The 1833 LM-5 and 1835 LM-12 demand the most searching and the largest budget.
