Authentication Guide: How to Spot a Real 1799 Bust Dollar

Historical Significance

The 1799 Bust Dollar stands as a captivating relic from America’s formative years in coinage. As one of the earliest silver dollars minted by the fledgling United States Mint, this coin embodies the young nation’s burgeoning economic independence and artistic ambitions. The Draped Bust design, featuring Liberty on the obverse and a small eagle on the reverse, was the work of Robert Scot and struck in limited quantities during a turbulent period of American history.

Identifying Key Markers

When authenticating a 1799 Bust Dollar, several critical diagnostic points demand careful examination. The genuine coin should weigh approximately 26.96 grams with a diameter of 39-40mm. The composition is 89.2% silver and 10.8% copper, giving it a distinctive weight and feel that counterfeits often struggle to replicate.

Weight and Metal Composition

Authentic 1799 Bust Dollars should register at 26.96 grams on a precision scale. Any significant deviation from this weight is an immediate red flag. The coin should not be magnetic – if a magnet sticks to your coin, it’s definitely a fake. The silver content should give the coin a specific ring when gently tapped, different from base metal counterfeits.

Die Markers and Design Details

Several die varieties exist for the 1799 date, with the most common being BB-141, BB-142, and BB-143. Each variety has distinctive die markers that experts use for authentication. Pay close attention to the spacing between stars, the shape of Liberty’s hair curls, and the arrangement of letters in “STATES OF AMERICA.”

Common Fakes and Alterations

Counterfeiters have targeted the 1799 Bust Dollar for decades. Common fakes include cast copies with porous surfaces, spark erosion counterfeits with mushy details, and altered dates where a “9” has been added to a genuine 1798 coin. The most sophisticated fakes are struck counterfeits made from genuine coin dies, which can be extremely difficult to detect without professional authentication.

Surface Examination

Genuine 1799 Bust Dollars typically show even wear patterns consistent with their age. Look for natural patina and toning that develops over centuries of circulation. Be wary of coins with unusually bright surfaces, as this may indicate cleaning or artificial toning. The coin should show appropriate friction on the high points – Liberty’s hair, the eagle’s breast, and the wreath details.

Specific Problem Areas

Based on the forum discussion, several specific areas require careful examination on this particular coin:

• The scratch across Liberty’s face – this appears to be an old, toned-over mark but significantly impacts the coin’s eye appeal and CAC eligibility
• The dark spot on the last “S” in “STATES” – while some collectors see this as a minor issue, CAC has rejected coins for less severe toning spots
• Corrosion detected under the date and into the dentils – this is a serious concern that would likely prevent CAC approval
• Scratches behind Liberty’s head on the obverse – these detract significantly from the coin’s overall appearance

Testing Methods

Professional authentication involves multiple testing methods:

Visual Inspection

Examine the coin under magnification (10x minimum) in good lighting. Look for proper detail sharpness, especially in the hair curls and eagle feathers. Genuine coins show crisp detail even in worn areas, while fakes often have mushy or missing details.

Specific Gravity Test

Calculate the specific gravity by weighing the coin in air and then in water. The result should be approximately 10.3 for a genuine silver dollar. This test helps detect coins that have been plated or made from incorrect alloys.

Die Match Analysis

Compare your coin’s die characteristics to known genuine examples. Pay particular attention to die cracks, repunching, and other unique features that can be matched to documented specimens.

Surface Analysis

Use a microscope to examine the surface at high magnification. Look for casting porosity, tool marks from alterations, or unusual surface textures that might indicate modern cleaning or artificial toning.

Common Fakes to Watch For

The forum discussion highlights several types of counterfeits that plague the 1799 Bust Dollar market:

The most dangerous fakes are those that combine genuine elements with alterations. A genuine 1798 coin with a 9 added to the date, or a genuine coin from another year with the date altered to 1799, can fool even experienced collectors.

Modern counterfeits often show these telltale signs:

• Incorrect weight (usually too light or too heavy)
• Wrong diameter or thickness
• Inconsistent edge reeding
• Unnatural surface texture
• Incorrect die characteristics for the variety

Authentication Conclusion

Based on the detailed forum analysis, this particular 1799 Bust Dollar presents a challenging authentication case. While the coin appears to be a solid AU-53 with original surfaces, several factors would likely prevent CAC approval:

1. The prominent scratch across Liberty’s face, despite appearing old and toned
2. Corrosion detected under the date and into the dentils
3. Multiple scratches behind Liberty’s head
4. Potentially insufficient luster for CAC standards

The consensus among experienced collectors suggests this coin would not receive a CAC sticker in its current condition. However, the coin appears to be a genuine, original 1799 Bust Dollar that has been accurately graded by PCGS.

Final Assessment

For collectors considering this coin, the authentication appears sound – it’s likely a genuine 1799 Bust Dollar with honest wear and original surfaces. The technical grade of AU-53 seems appropriate given the wear patterns observed. However, the surface issues (scratches, corrosion, toning spots) significantly impact the coin’s eye appeal and market value.

This case illustrates the importance of professional authentication and the value of CAC approval in today’s market. Even genuine, accurately graded coins can fail to receive stickers due to surface issues that don’t affect their authenticity but do impact their desirability to premium collectors.

For serious collectors, this coin might represent good value as a type coin or for a collector focusing on die varieties rather than condition rarity. However, those seeking investment-grade examples would be better served looking for coins with cleaner surfaces and stronger eye appeal, even if they command higher prices.

Remember that authentication is an ongoing process – even experts can disagree on borderline cases. When in doubt, seek multiple opinions from reputable dealers and consider professional authentication services for high-value coins like the 1799 Bust Dollar.
