Is Your LE Bruun Sale Part IV Medal Real? How to Spot a Fake

Introduction

In today’s market, where counterfeits are becoming increasingly sophisticated, knowing the specific diagnostic points for this medal is absolutely critical for collectors and investors alike.

Historical Significance

The Danish abolition of slavery in North America medal from the LE Bruun Sale Part IV represents a pivotal moment in both numismatic and historical contexts. This medal commemorates Denmark’s 1792 abolition of the transatlantic slave trade, making it not just a collectible but a significant artifact of human rights history. The Danish West Indies, which later became the US Virgin Islands, and Danish India were central to this narrative, as these colonies were directly affected by this legislation.

Identifying Key Markers

When authenticating this medal, several key markers must be examined closely:

Weight Specifications

Authentic examples of this medal should weigh within specific parameters depending on their composition. Bronze versions typically weigh between 25-30 grams, while silver versions are heavier at approximately 35-40 grams. Gold-plated versions fall somewhere in between. Any significant deviation from these weights should raise immediate red flags about authenticity.

Magnetic Properties

Testing for magnetic properties is crucial in authentication. Bronze medals should show no magnetic attraction, while silver versions may exhibit minimal response due to trace elements. Gold-plated versions might show slight magnetic properties if the underlying base metal contains iron content. Complete magnetic attraction indicates a counterfeit, likely made from modern base metals.

Die Markers and Details

Authentic medals display specific die markers that counterfeiters often miss. Examine the sharpness of the lettering, particularly around the date and inscriptions. The medal’s edge should show consistent reeding or lettering patterns. Look for the specific die cracks or polishing marks that appear on genuine examples. The relief and depth of the design elements should be consistent with period-appropriate minting techniques.

Surface Patina and Wear Patterns

Natural aging patterns on bronze medals create a distinctive patina that develops over 200+ years. Authentic examples show uneven oxidation, with darker areas in recessed details and lighter highlights on raised surfaces. Counterfeits often display artificially aged surfaces or unnaturally uniform patination. Examine the wear patterns – genuine pieces show logical wear consistent with their supposed age and handling history.

Metal Composition Testing

Professional authentication should include XRF (X-ray fluorescence) testing to verify metal composition. Bronze medals should show copper and tin content consistent with 18th-century metallurgy. Silver versions must contain appropriate silver content (typically .800 to .925 fineness). Any modern alloy compositions or unexpected trace elements indicate forgery.

Common Fakes and Variations

Several counterfeit types have emerged in the market:

• Modern cast reproductions using incorrect alloys
• Silver-plated base metal fakes designed to deceive basic testing
• Altered dates or mint marks on genuine but less valuable medals
• Contemporary restrikes passed off as original issues

The most sophisticated fakes often combine multiple deception techniques, including correct weight but wrong metal composition, or proper alloy but incorrect die characteristics.

Testing Methods

Comprehensive authentication requires multiple testing approaches:

Visual Examination

Begin with careful visual inspection under magnification. Look for casting bubbles, file marks, or modern tooling marks. Examine the medal’s edge for signs of casting or improper finishing. Check for consistent strike quality across the entire surface.

Weight and Dimension Verification

Verify weight using a precision scale accurate to 0.01 grams. Measure diameter and thickness with calipers, comparing to known authentic specifications. Even minor variations can indicate problems.

Magnetic Testing

Use a strong neodymium magnet to test for magnetic properties. Perform the test in multiple orientations and locations on the medal. Document any magnetic response, as this provides crucial authentication data.

Advanced Testing

Professional authentication should include specific gravity testing, XRF analysis, and microscopic examination of surface features. These tests can detect modern manufacturing techniques invisible to the naked eye.

Market Context and Value Considerations

The LE Bruun Sale Part IV demonstrated the strong market demand for these medals, with many lots selling for double or triple high estimates. The competition was particularly intense for high-grade examples, with one bidder acquiring approximately 90% of available lots. This market activity has unfortunately created incentives for sophisticated counterfeiting operations.

Conclusion

The Danish abolition of slavery medal represents both a significant historical artifact and a challenging authentication target. With prices reaching thousands of dollars for authentic examples, and the historical importance of these pieces, proper authentication is essential for collectors and investors. By understanding the specific diagnostic points – weight, magnetic properties, die markers, and proper testing methods – collectors can better protect themselves from sophisticated counterfeits flooding the market. When in doubt, professional authentication by a reputable service is always recommended before making significant purchases.
