Is Your Bust Half Dime Real? Expert Authentication Guide for Capped Bust Half Dimes

Historical Significance

The Capped Bust Half Dime represents one of the most captivating periods in early American numismatics. Minted from 1829 to 1837, these diminutive silver coins served as essential circulating currency during America’s formative years. At roughly the size of a modern nickel but containing significantly more silver content, these coins were practical for everyday transactions while showcasing the artistic craftsmanship of early American minting.

The series is particularly notable for its distinctive design featuring Liberty wearing a Phrygian cap, a symbol of freedom dating back to ancient Rome. The reverse displays a heraldic eagle with a shield, holding arrows and an olive branch – imagery that would become iconic in American coinage. The 1835 date mentioned in our discussion represents one of the more accessible issues in the series, making it an excellent entry point for collectors seeking to build a meaningful collection.

Identifying Key Markers

Weight and Metal Composition

Authentic Capped Bust Half Dimes were struck in .900 fine silver with a total weight of 1.35 grams. This precise specification is crucial for authentication. Modern counterfeits often fail this basic test – many will be either underweight due to silver shortages in production or overweight due to incorrect alloy mixtures. Always verify weight using a precision scale accurate to at least 0.01 grams.

Magnetic Properties Test

Since these coins are composed of 90% silver and 10% copper, they should exhibit no magnetic attraction whatsoever. Any magnetic response indicates the presence of ferrous metals and confirms a counterfeit. This simple test can quickly eliminate many modern fakes that use steel cores or other magnetic materials to simulate weight.

Die Markers and Design Details

Authentic Capped Bust Half Dimes display specific die characteristics that are extremely difficult for counterfeiters to replicate accurately. For the 1835 date specifically, examine the following:

• The hair detail on Liberty’s cap should show fine, crisp strands with natural flow and depth
• The stars on the obverse should be evenly spaced with distinct, pointed rays
• The eagle’s feathers on the reverse must show individual delineation with natural overlapping patterns
• The shield lines should be straight and parallel, not wavy or irregular

Pay particular attention to the eagle’s eye – authentic examples show a distinct, well-defined eye with proper depth, while counterfeits often render this feature as a simple flat impression.

Edge Reeding Examination

The edge of authentic specimens features 118 reeds (small vertical lines). Counterfeit coins frequently display incorrect reed counts or irregular spacing. Use a magnifying glass to count the reeds carefully – this is a common point where fakes are exposed.

Common Fakes and Their Characteristics

Modern Counterfeits

The market has seen a surge in Chinese-produced counterfeits of early American coinage, including the Capped Bust Half Dime. These fakes often share several telltale characteristics:

“The whole group of about 20 half disme were taken along with 20 Bust Halfs, 20 or so high grade Morgans, plus a lot more. Some of them showed up later on auction sites.”

This collector’s experience highlights a disturbing trend where stolen authentic coins are replaced with high-quality counterfeits on auction platforms. The sophistication of modern fakes makes authentication expertise more critical than ever.

Cast Counterfeits

Older cast counterfeits are typically easier to identify through their porous surfaces and lack of fine detail. However, modern die-struck counterfeits can be remarkably deceptive. Look for these red flags:

• Weak or missing details in the hair strands and eagle feathers
• Incorrect silver content (often too low or sometimes too high with added metals)
• Improper toning patterns that appear unnatural or artificially aged
• Incorrect die alignment or rotation

Testing Methods for Authentication

Professional Authentication Services

For high-value specimens or when uncertainty exists, professional authentication through PCGS, NGC, or ANACS provides definitive verification. These services employ multiple experts and advanced technology to examine coins under magnification and through various testing methods.

Specific Gravity Testing

This non-destructive test compares the coin’s density to that of pure silver. Authentic Capped Bust Half Dimes should register between 10.3 and 10.5 g/cm³. Deviations beyond this range suggest counterfeit materials or incorrect alloy compositions.

Die State Analysis

Experienced collectors can identify specific die states and marriage varieties. The 1835 date, for instance, has several known die varieties with distinctive characteristics. Consulting specialized references and comparing your specimen to documented examples is essential for authentication.

Surface Analysis

Examine the coin under 10x magnification for these authenticity indicators:

• Crystallized structure typical of 19th-century silver coins
• Natural flow lines from original striking
• Appropriate wear patterns consistent with the coin’s grade
• Absence of modern tooling marks or artificial aging

Market Value and Collectibility

Current Market Conditions

As noted in the discussion, “There isn’t a lot of collecting pressure on this series, meaning one can still find nice coins for a fair price.” This presents both opportunities and challenges for collectors. The relative affordability of Capped Bust Half Dimes in circulated grades makes them accessible, but it also means fewer resources are dedicated to studying and documenting the series compared to more popular denominations.

Value Ranges by Grade

XF-AU (Extremely Fine to About Uncirculated) specimens like the 1835 mentioned typically range from $200 to $500 depending on specific die variety and eye appeal. Higher-grade examples can command significantly more, while well-circulated pieces may be available for under $100.

Completing a Collection

The series spans only nine years (1829-1837), making it possible to assemble a complete date set. However, the various die varieties within each year can expand a collection considerably. The original poster’s experience of having “about 20 half disme” demonstrates the depth possible within this seemingly simple series.

Authentication Best Practices

Documentation and Provenance

The unfortunate theft experience shared by one collector underscores the importance of maintaining detailed records. Always:

• Photograph coins with high-resolution images
• Keep receipts and transaction records
• Document specific die markers and characteristics
• Store information securely, preferably off-site

Secure Storage Recommendations

Following a significant loss, the collector mentioned storing new acquisitions “off site in a safe used for Narcotics and that is alarmed and insured.” This level of security, while extreme for most collectors, highlights the value of proper storage:

• Use bank safety deposit boxes for the most valuable pieces
• Invest in high-quality home safes with fire and theft protection
• Consider alarm systems and insurance coverage
• Maintain an updated inventory with photographs

Conclusion

The Capped Bust Half Dime series offers collectors an accessible entry into early American coinage with significant historical significance. However, the prevalence of counterfeits makes authentication knowledge essential. By understanding the specific weight, magnetic properties, die markers, and common fake characteristics, collectors can protect themselves from costly mistakes.

Remember that authentication is both an art and a science. While the tests and markers discussed provide excellent guidance, nothing replaces experience and expert consultation when dealing with potentially valuable specimens. The small size of these coins belies their importance in American numismatic history and their potential value to knowledgeable collectors.

For those interested in pursuing this series, start with well-documented, authenticated examples and gradually build your expertise. The satisfaction of holding a genuine piece of early American commerce, properly authenticated and understood, is one of numismatics’ greatest rewards.
