Is Your Bust Boo-Boos Post Your Bust Errors Real? How to Spot a Fake

Introduction

With counterfeits flooding the market, knowing the specific diagnostic points for this item is critical. The world of Bust coin errors is filled with fascinating anomalies, but it’s also a prime target for sophisticated fakes. Whether you’re a seasoned collector or just starting out, understanding the key markers of authenticity can save you from costly mistakes.

Historical Significance

Bust coinage represents a pivotal era in American numismatics, spanning from the late 18th to mid-19th centuries. These coins were struck during the early years of the United States Mint, making them historically significant and highly collectible. The errors discussed in this thread—from unlettered edges to off-center strikes—represent rare manufacturing anomalies that occurred during this formative period.

Identifying Key Markers

Weight Specifications

Authentic Bust coins have specific weight requirements that vary by denomination and year. For example:

• Bust half dollars (1807-1836): 13.48 grams (when silver content was .8924 fine)
• Bust quarters (1796-1838): 6.74 grams
• Bust dimes (1796-1837): 2.70 grams

Modern counterfeits often fail to match these precise specifications. Always weigh your coin on a calibrated digital scale. A deviation of more than 0.1 grams should raise immediate concerns.

Magnetic Properties

Authentic silver and gold Bust coins are non-magnetic. If your coin is attracted to a magnet, it’s almost certainly a fake. Some counterfeits use magnetic metals as a core with a thin silver coating, so this test is crucial.

Die Markers and Diagnostics

Each Bust coin variety has specific die markers that can help authenticate it. The forum discussion mentions several key diagnostic features:

"That is a well known die crack for the marriage." – BustDMs

Die cracks, repunched dates, and other die varieties are well-documented in specialized references. The absence of expected die markers or the presence of unusual ones can indicate a counterfeit.

Common Fakes and Alterations

The forum reveals several types of errors that have been faked or altered:

• Unlettered edge capped bust half dollars
• Off-center strikes
• Double strikes with dentil tracks
• Edge lettering variations

Counterfeiters often target these dramatic errors because they command premium prices. Be particularly wary of coins that seem too good to be true or lack proper documentation.

Testing Methods

Visual Inspection

Examine your coin under magnification (10x loupe minimum). Look for:

• Sharpness of detail – genuine coins have crisp, well-defined features
• Metal flow lines – authentic coins show natural flow patterns
• Edge characteristics – examine reeding, lettering, and overall edge quality

Specific Gravity Test

This test helps verify silver content:

1. Weigh the coin in air (W_air)
2. Weigh it suspended in water (W_water)
3. Calculate: Specific Gravity = W_air / (W_air – W_water)

Silver should read approximately 10.3-10.5. Significant deviations suggest a fake.

Edge Lettering Verification

The forum mentions unlettered edge coins as particularly rare:

"My unlettered edge capped bust half dollar, ex: Dosier, Hilgard, Logan. Likely the second finest unlettered edge CBH of no more than a dozen known…" – BustDMs

Examine edge lettering carefully. Authentic lettering should be:

• Evenly spaced and properly aligned
• Consistent in depth and character
• Free from modern tool marks or irregularities

Die Crack Analysis

Die cracks are natural aging features of dies. Authentic die cracks:

• Follow logical paths based on die stress patterns
• Show appropriate wear characteristics
• Match known die states for the variety

Common Error Types and Their Markers

Unlettered Edge Errors

These are among the rarest and most valuable errors. Authentication points:

• Verify weight and diameter match specifications
• Examine the edge under magnification for signs of post-mint alteration
• Check for proper upset rim characteristics

Off-Center Strikes

The forum discusses several off-center examples:

"This is (I think) the largest offcenter large size bust quarter known." – scubafuel

Authentic off-center strikes show:

• Natural metal flow and distortion
• Proper weight (no metal loss)
• Appropriate die wear patterns

Double Strikes

Double strikes are faked by altering single coins. Look for:

• Natural rotation between strikes
• Appropriate metal flow where strikes overlap
• Consistent die wear across both strikes

Edge Errors

Various edge errors are discussed, including:

• Double edge lettering
• Missing edge lettering
• Edge planchet flaws

Red Flags for Counterfeits

Price Too Good to Be True

If a rare error coin is priced significantly below market value, be extremely cautious. The forum mentions several high-value coins:

"My large size was just 5% off center but on a very rare over-date and in gem condition, selling in the 25k range." – BustDMs

Lack of Provenance

Authentic rare coins typically have documented history. Be suspicious of coins with:

• No previous auction records
• Missing or questionable certifications
• Unusual storage or preservation methods

Modern Manufacturing Marks

Look for signs of modern production:

• Machine-made marks or scratches
• Unnatural surface texture
• Incorrect aging characteristics

Authentication Resources

Professional Grading Services

Consider third-party authentication from reputable services like:

• PCGS (Professional Coin Grading Service)
• NGC (Numismatic Guaranty Corporation)
• ANACS (American Numismatic Association Certification Service)

Reference Materials

Essential references include:

• Bowers and Merena auction catalogs
• Specialized error coin references
• Online error coin databases

Conclusion

The world of Bust coin errors offers fascinating collecting opportunities, but it also presents significant authentication challenges. By understanding the specific diagnostic points—weight, magnetic properties, die markers, and testing methods—you can better protect yourself from counterfeits. Remember that rare errors command premium prices, making them prime targets for sophisticated fakes. When in doubt, seek professional authentication and always buy from reputable dealers. The coins discussed in this forum thread represent some of the most desirable and challenging errors to authenticate, making them perfect examples of why expertise matters in this specialized field.

Happy collecting, and may all your Bust Boo-Boos be authentic!
