Is Your Doily Saint Finally Real? How to Spot a Fake

Historical Significance

The Saint-Gaudens Double Eagle, affectionately nicknamed the “Doily” Saint by collectors, represents one of the most iconic designs in American numismatic history. Designed by famed sculptor Augustus Saint-Gaudens at the request of President Theodore Roosevelt, these $20 gold pieces were minted from 1907 to 1933 and are renowned for their stunning high-relief design featuring Liberty striding forward on the obverse and a majestic eagle in flight on the reverse.

The 1924 issue, particularly in MS62 condition with CAC (Certified Acceptance Corporation) verification, represents a significant find for collectors. While not as rare as the famed 1927-D or 1931-D issues, the 1924 Saint-Gaudens Double Eagle still commands attention due to its historical importance and the beauty of Saint-Gaudens’ design. The CAC sticker indicates that the coin meets strict quality standards for its assigned grade, adding an extra layer of desirability and confidence for collectors.

Identifying Key Markers

When authenticating a Doily Saint, several critical markers must be examined. The weight of a genuine Saint-Gaudens Double Eagle should be precisely 33.431 grams (or 516 grains). Any deviation from this specification should immediately raise suspicion. The coin’s diameter measures 34mm, and its thickness is 2mm.

The metal composition is 90% gold and 10% copper alloy, giving it a distinctive color and heft. A genuine coin will not be attracted to a magnet, as gold is non-magnetic. However, sophisticated counterfeits may use non-magnetic metals in their core, so magnetic testing alone is insufficient for authentication.

Die markers are crucial for authentication. For the 1924 issue, examine the reverse for specific die characteristics. Look for the positioning of the eagle’s wing tips relative to the lettering, the sharpness of the olive branch details, and the definition of the sun’s rays. Each die has unique characteristics that can be compared to known genuine examples. The obverse should show Liberty’s torch and olive branch held in specific positions relative to her gown folds.

Common Fakes and Their Characteristics

Counterfeiters have become increasingly sophisticated in replicating Saint-Gaudens Double Eagles. Common fakes include cast counterfeits, which often show porosity or bubbles in the metal, and transfer-die counterfeits, which can be extremely deceptive. Transfer-die counterfeits are made by creating dies from genuine coins, resulting in excellent detail but often with slight distortions or weaknesses in the design elements.

Chinese counterfeits have flooded the market in recent years, with many showing excellent visual appeal but failing weight and metallurgical tests. These fakes often use tungsten cores plated with gold, achieving the correct weight but failing specific gravity tests. Some sophisticated fakes use gold-plated tungsten with the correct dimensions but incorrect specific gravity due to the density difference between tungsten and gold.

Another common fake technique involves creating coins from gold-colored base metals that match the correct weight through careful alloying. These can be particularly deceptive because they pass basic visual and weight tests but fail more sophisticated authentication methods.

Testing Methods

Professional authentication of a Doily Saint should employ multiple testing methods. Start with a visual examination under magnification, checking for proper detail sharpness, correct lettering style, and appropriate surface texture. Use a digital scale accurate to 0.001 grams to verify the weight precisely matches 33.431 grams.

Specific gravity testing provides excellent results for gold coins. This test measures the density of the coin by weighing it in air and then in water, calculating whether the density matches that of 90% gold alloy. The specific gravity of a genuine Saint-Gaudens Double Eagle should be approximately 17.2-17.3 g/cm³.

Advanced collectors and dealers may employ X-ray fluorescence (XRF) testing, which analyzes the metal composition without damaging the coin. This technology can detect the exact percentages of gold, silver, and copper, as well as identify any base metal cores or unexpected alloying elements.

Die variety attribution can also aid authentication. For the 1924 issue, consult specialized references that document known die marriages and their specific characteristics. Compare your coin’s features to documented genuine examples, paying particular attention to mintmark style and position, date style, and reverse design elements.

Market Considerations and Value

The market for Saint-Gaudens Double Eagles remains strong, with values influenced by grade, eye appeal, and certification. An MS62 1924 Saint with CAC verification represents a solid investment piece, offering a balance between affordability and collectible value. CAC-stickered coins typically command premiums of 10-20% over non-CAC examples in the same grade.

When purchasing, consider the source carefully. Reputable dealers with established track records provide better protection against counterfeits than unknown sellers. Third-party certification from PCGS or NGC remains the gold standard for authentication and grade verification. The CAC verification adds another layer of confidence in the grade and eye appeal.

Be aware that bidding dynamics in online auctions can be misleading. As noted in collector discussions, losing a bid by a small margin doesn’t necessarily mean the winning bidder’s maximum was only slightly higher. Many bidders use proxy bidding systems, where their maximum bid is only revealed if challenged by another bidder reaching that threshold.

Conclusion

The Doily Saint remains one of the most beautiful and historically significant coins in American numismatics. Whether you’re a seasoned collector or just beginning your journey, understanding the authentication requirements for these coins is essential. The 1924 issue in MS62 with CAC verification represents an excellent opportunity to own a piece of numismatic history at a reasonable price point.

Remember that authentication requires multiple testing methods and careful comparison to known genuine examples. Don’t rely on any single test, and when in doubt, consult with professional authenticators or experienced dealers. The investment in proper authentication protects not only your financial investment but also ensures you’re preserving genuine pieces of American history for future generations.

For collectors who have finally acquired their Doily Saint, the satisfaction of owning such a magnificent coin is well worth the effort required to ensure its authenticity. With counterfeits becoming increasingly sophisticated, the knowledge and testing methods outlined here provide the tools needed to make informed collecting decisions and build a collection of genuine, historically significant coins.
