Counterfeit Coin Detection – 1876-CC 20 Cent Piece

The 1876-CC 20 Cent Piece is one of the most desirable coins in U.S. numismatics, owing to its low mintage, historical significance, and unique design. Produced during a short-lived experiment with a denomination between the dime and quarter, the 20-cent coin remains a target for counterfeiters attempting to capitalize on its rarity and value. Learning to identify counterfeit versions of this coin is crucial for collectors and investors alike.

The History of the 1876-CC 20 Cent Piece

The 20-cent piece was introduced in 1875 but was quickly discontinued due to confusion with the quarter dollar, as both coins were of similar size and appearance. In 1876, the Carson City Mint produced just 10,000 examples before ceasing production. Over time, most of these coins were melted down, leaving fewer than 20 known specimens in existence today. Their scarcity and connection to the fabled Carson City Mint make them incredibly valuable, with genuine examples commanding six-figure prices.

Unfortunately, their prestige has also made them a favorite target for counterfeiters. Sophisticated fakes can fool even experienced collectors if they fail to scrutinize the coin’s characteristics carefully.

Key Characteristics of the 1876-CC 20 Cent Piece

Authenticating an 1876-CC 20 Cent Piece begins with an understanding of its design and die characteristics. The coin features Liberty seated on a rock on the obverse, with a cap and pole in one hand and a shield in the other. The reverse depicts a heraldic eagle, surrounded by the inscriptions “UNITED STATES OF AMERICA” and “TWENTY CENTS.” Below the eagle is the “CC” mintmark, denoting the Carson City Mint.

The coin has a diameter of 22 millimeters and weighs approximately 5 grams. It has a plain edge—a distinguishing feature compared to the reeded edge of a quarter. These details are essential for spotting alterations or outright counterfeits.

Common Counterfeiting Methods

1. Altered Dates:
   One common tactic involves altering the date on an 1875-CC 20 Cent Piece to mimic the rare 1876-CC variety. Counterfeiters use engraving tools to change the final digit of the date. Collectors should examine the date under magnification for signs of tooling, such as inconsistent digit shapes, unnatural spacing, or irregular surfaces.
2. Added Mintmarks:
   Another frequent method involves adding a counterfeit “CC” mintmark to a genuine Philadelphia-minted 20-cent coin. Inspect the mintmark closely to ensure it aligns correctly with the coin’s surface and matches known genuine examples in size, shape, and position.
3. Cast Counterfeits:
   Poor-quality counterfeits are often cast rather than struck, leading to soft details, porous surfaces, and incorrect weights. Authentic 1876-CC coins will have sharp details and consistent luster, hallmarks of the minting process.

Tips for Authentication

• Weight and Dimensions: Use a precise scale and calipers to verify the coin’s weight and diameter. Deviations from the standard specifications are a red flag.
• Edge Examination: Ensure the coin has a plain edge rather than a reeded one, as some counterfeits are altered from quarter-dollar blanks.
• Professional Grading: Always buy certified examples graded by trusted third-party grading services like PCGS or NGC. Their expertise significantly reduces the risk of purchasing a counterfeit.

Conclusion

The 1876-CC 20 Cent Piece is a rarity treasured by collectors, but its high value makes it a magnet for counterfeiting. By studying the coin’s key characteristics and understanding common counterfeit methods, collectors can protect themselves from fraudulent coins. For those unsure about their ability to authenticate a coin, consulting with a professional or acquiring certified specimens is the safest way to ensure a sound investment.
