Is Your 1883 Hawaiian Dollar Real? How to Spot a Fake

Historical Significance

The 1883 Hawaiian Dollar stands as a remarkable artifact of American numismatic history. Struck at the San Francisco Mint, these coins were King Kalākaua’s bold attempt to establish a modern monetary system for the Kingdom of Hawaii. Composed of 90% silver and 10% copper, each coin weighs precisely 26.73 grams and measures 38.1mm in diameter. The obverse showcases King Kalākaua’s profile, while the reverse displays the Hawaiian coat of arms—a design that captures the cultural identity of a nation on the cusp of profound change.

Authentication Guide: Key Diagnostic Points

With counterfeits flooding the market, knowing the specific diagnostic points for this item is critical.

Weight and Dimensions

Authentic 1883 Hawaiian Dollars should weigh exactly 26.73 grams with a tolerance of ±0.1 grams. The diameter must measure precisely 38.1mm. Any deviation from these specifications should raise immediate red flags. Counterfeiters often struggle to replicate the exact weight, making this one of the most reliable authentication methods.

Magnetic Properties

Being composed of 90% silver, authentic 1883 Hawaiian Dollars should not be magnetic. If a strong magnet attracts your coin, it’s almost certainly a fake. Some sophisticated counterfeits use magnetic materials as cores with silver plating, so a non-magnetic test alone isn’t conclusive but is an essential first step.

Die Markers and Design Details

Authentic specimens show specific die characteristics that are difficult to replicate perfectly. Examine the fine details of King Kalākaua’s portrait, particularly around the ear and hair. The feathers on the Hawaiian coat of arms should show crisp, individual detail. Many counterfeits appear mushy or lack the sharp relief found on genuine examples.

Edge Examination

The edge of an authentic 1883 Hawaiian Dollar should be reeded with 150 reeds. Using a magnifying glass, count the reeds to ensure accuracy. Counterfeiters often get this detail wrong, using too few or too many reeds, or creating an edge that appears uneven or poorly finished.

Common Fakes and Counterfeits

Several types of counterfeits exist in the marketplace. The most common are modern cast counterfeits, which often show a rough, porous surface texture and lack the sharp details of genuine coins. These are typically made from base metals and may have incorrect weights.

Another type involves genuine silver coins that have been altered to resemble 1883 Hawaiian Dollars. This might include adding fake mint marks or altering the date. These can be particularly deceptive because they contain the correct metal content.

Counterstamped coins present another challenge. As discussed in the forum thread, coins with contemporary countermarks like “P G” or “R” have appeared on the market. While these may be authentic countermarks from the Provisional Government era, they significantly affect the coin’s value and should be properly documented by grading services.

Testing Methods

Professional Authentication

For high-value specimens, professional authentication is recommended. Third-party grading services use advanced techniques including specific gravity testing, microscopic examination, and comparison with known genuine examples. They can also provide proper attribution for countermarks and other modifications.

Specific Gravity Test

This simple test can help verify silver content. The specific gravity of pure silver is 10.49 g/cm³. To perform this test, you’ll need a precise scale and a water displacement container. The calculation involves weighing the coin in air and then in water, with the ratio between these weights indicating the coin’s density.

Visual Inspection Under Magnification

Using a 10x loupe or microscope, examine the coin’s surface for signs of casting, such as bubbles or pits. Look for flow lines that indicate the metal flowed during striking – these are extremely difficult to replicate in counterfeits. Pay special attention to the fine details around the date and mint mark.

Countermarks and Modifications

The forum discussion highlights an interesting case of a coin with a “P G” counterstamp. While some collectors speculate this could be a Provisional Government countermark from the era following the monarchy’s overthrow, there’s no documented evidence of such countermarks being officially applied to Hawaiian coinage.

TPG (Third Party Grading) services typically label such modifications as “countermarked” rather than “damaged,” though this designation can significantly impact the coin’s market value. Some collectors find these modified pieces intriguing as historical curiosities, while others prefer unaltered specimens.

Market Considerations

Authentic 1883 Hawaiian Dollars in circulated condition typically range from $1,500 to $3,000, depending on grade and eye appeal. Uncirculated examples can command $5,000 to $10,000 or more. Countermarked specimens generally sell for less, though exceptionally rare or historically significant countermarks might add value for certain collectors.

When purchasing, be particularly cautious of deals that seem too good to be true. The combination of historical significance and silver content makes these coins attractive targets for counterfeiters. Always buy from reputable dealers who offer return privileges and authentication guarantees.

Conclusion

The 1883 Hawaiian Dollar remains one of the most fascinating and collectible coins in American numismatics. Whether you’re drawn to its historical significance, its silver content, or the mystery of potential countermarks, proper authentication is essential. By understanding the key diagnostic points – weight, magnetic properties, die markers, and common fakes – you can protect yourself from counterfeits and build a collection you can be confident in.

Remember that even experts can be fooled by sophisticated counterfeits, so when in doubt, seek professional authentication. The peace of mind that comes with knowing your coin is genuine is worth the investment, especially for a piece of history as significant as the 1883 Hawaiian Dollar.
