Is Your 1959D Cent Real? How to Spot a Fake

Historical Significance

The 1959D Lincoln cent stands as one of modern numismatics’ most controversial coins. What began as a simple minting error discussion has morphed into a complex authentication challenge that has split collectors and grading services alike. The controversy centers around coins bearing the 1959 date paired with a D mint mark – a combination that should not exist according to official records.

Identifying Key Markers

When authenticating a 1959D cent, several critical diagnostic points must be examined. The weight should measure exactly 3.11 grams for a genuine copper-alloy cent. Any deviation beyond 0.1 grams should raise immediate red flags. Use a precision digital scale calibrated to at least 0.01 grams for accurate measurement.

Magnetic properties provide another crucial test. Authentic 1959D cents (if they exist) would be non-magnetic, as they were struck in bronze. If your coin exhibits any magnetic attraction, it’s almost certainly a counterfeit or altered piece.

Die markers require careful examination under magnification. Look for specific characteristics including:

• Repunched mint marks or date anomalies
• Die cracks or breaks in unusual patterns
• Inconsistent letter spacing or alignment
• Anomalous die polish lines

Common Fakes to Watch For

The market has seen numerous counterfeit 1959D cents, typically falling into these categories:

1. Altered 1959 Philadelphia cents with added D mint marks
2. 1960D cents with altered dates
3. Contemporary counterfeits using incorrect metal compositions
4. Cast copies with telltale surface irregularities

The most sophisticated fakes often involve genuine 1959 cents that have been altered. These can be particularly deceptive because they share the correct weight and non-magnetic properties of authentic coins.

Testing Methods

Professional authentication requires multiple testing approaches:

Visual Inspection

Examine the coin under 10x magnification, paying special attention to the junction between the date and mint mark. Authentic coins show natural die flow, while fakes often display tool marks or unnatural transitions.

Specific Gravity Test

Calculate the specific gravity by weighing the coin in air and then suspended in water. A genuine copper-alloy cent should register between 8.80 and 8.92 g/cm³.

Microscopic Analysis

Under high magnification, authentic coins show consistent metal flow patterns and die wear. Fakes often reveal casting bubbles, file marks, or other manufacturing artifacts.

Advanced Testing

X-ray fluorescence (XRF) analysis can definitively determine the metal composition. This test is particularly useful for identifying contemporary counterfeits that use incorrect alloys.

Authentication Checklist

When examining a potential 1959D cent, systematically work through this checklist:

• [ ] Verify weight: 3.11 ± 0.01 grams
• [ ] Test for magnetism: should be non-magnetic
• [ ] Examine die markers under magnification
• [ ] Check specific gravity: 8.80-8.92 g/cm³
• [ ] Look for signs of alteration or tooling
• [ ] Compare with known genuine examples

Professional Authentication

For high-value specimens, professional authentication is essential. Reputable third-party grading services can provide expert analysis and certification. However, be aware that even major grading services have had controversies regarding these coins, as evidenced by recent forum discussions about PCGS’s handling of 1959D cent attributions.

Market Impact

The uncertainty surrounding 1959D cents has created a unique market dynamic. Some collectors actively seek these coins despite authentication challenges, while others avoid them entirely. Prices can vary dramatically based on perceived authenticity and provenance.

Important Warning: The 1959D cent remains one of the most frequently counterfeited modern coins. Exercise extreme caution when purchasing, and always insist on return privileges and authentication guarantees.

Conclusion

The 1959D Lincoln cent represents both a fascinating numismatic mystery and a significant authentication challenge. Whether these coins represent genuine mint errors, post-mint alterations, or outright counterfeits remains a subject of debate. What is certain is that collectors must approach these coins with heightened scrutiny and employ multiple authentication methods before making acquisition decisions.

The controversy surrounding these coins also highlights the importance of due diligence in numismatics. As the forum discussions demonstrate, even established grading services can face challenges in consistently attributing these pieces. For collectors, this means developing strong authentication skills and understanding the limitations of third-party grading when it comes to controversial varieties.

Remember: when in doubt about a 1959D cent’s authenticity, it’s better to walk away than to make an expensive mistake. The numismatic market has no shortage of genuine, fascinating coins that don’t carry the same authentication risks as these controversial pieces.
