Unearthing Treasure from the SS Central America
You don’t always need a dealer to find these historic coins. Here’s what to look for when searching through circulation or bulk lots for these 1857-S Double Eagles connected to the legendary SS Central America shipwreck.
Historical Significance
The 1857-S Double Eagle represents one of the most fascinating stories in American numismatics. These coins were part of a massive treasure shipment aboard the SS Central America when it sank in a hurricane off the coast of South Carolina in September 1857. The ship was carrying approximately 425,000 pounds of California gold from San Francisco to New York, including thousands of freshly minted double eagles.
For decades, this treasure lay undisturbed on the ocean floor until treasure hunter Tommy Thompson located the wreck in 1988. The recovery operation yielded a staggering amount of gold, including thousands of pristine 1857-S double eagles that had been preserved in near-perfect condition by the cold ocean depths.
Identifying Key Markers
When searching through bulk lots or estate sales, here’s what to look for:
- Date Range: Look specifically for coins dated 1857 with an ‘S’ mint mark (San Francisco)
- Condition: Many recovered coins show exceptional preservation with sharp details and minimal wear
- Weight and Composition: These are .900 fine gold, weighing 33.4 grams
- Diameter: 34mm across
The most valuable specimens will show full Liberty’s head detail and sharp feather definition on the eagle’s reverse. Some coins from the shipwreck recovery still retain their original luster and show minimal bag marks.
Circulation Finds vs. Treasure Coins
While the original treasure coins from Thompson’s recovery are well-documented and pedigreed, many 1857-S double eagles entered general circulation before the shipwreck. These non-shipwreck examples can still be found in:
- Old coin collections at estate sales
- Large lots of pre-1900 gold coins
- Occasionally in mixed currency collections
The key difference is provenance. Shipwreck coins typically come with documentation and often show remarkably preserved surfaces due to their protective encasement in the ocean floor.
Value Guide
Values for 1857-S double eagles vary significantly based on condition and provenance:
Common circulated examples: $2,000-$4,000
Uncirculated specimens: $4,000-$10,000
Shipwreck coins with documentation: $10,000-$25,000+
Exceptional specimens with rare die varieties: $25,000+
The gold content alone (approximately 0.9675 troy ounces) provides a base value around $1,800-$2,000 at current gold prices, but numismatic premiums can be substantial.
Authentication Tips
When examining potential specimens:
- Check for proper weight (33.4 grams)
- Verify the date and mint mark
- Examine the edge for reeding
- Look for signs of modern counterfeiting (casting bubbles, incorrect relief)
- Consider professional authentication for high-value pieces
Many counterfeiters target these coins due to their value, so caution is warranted when purchasing from unfamiliar sources.
Where to Search
Your best opportunities for finding these coins include:
- Large estate collections being liquidated
- Bank rolls of older coins (though rare in modern times)
- Online auctions with poor photography where details might be missed
- Antique shops where dealers may not recognize the coin’s significance
The most successful hunters develop relationships with estate sale companies and learn to recognize when collections might contain gold coins from the 1850s-1930s era.
The Tommy Thompson Connection
The recent release of treasure hunter Tommy Thompson from prison after refusing to disclose the location of 500 additional gold coins has renewed interest in these historic pieces. Thompson’s discovery of the SS Central America treasure in the late 1980s was one of the greatest archaeological finds in American history, yielding millions in gold coins and bars.
The coins minted from recovered gold bars serve as modern commemoratives of this historic find. Some collectors seek both the original 1857-S double eagles and the modern restrikes made from the recovered treasure’s gold content.
Conclusion
The 1857-S Double Eagle represents both a significant piece of American history and a potentially valuable numismatic find. Whether you’re searching through bulk lots, attending estate sales, or examining inherited collections, knowing what to look for can help you identify these treasures when they appear. The combination of historical significance, gold content, and the romantic story of the SS Central America makes these coins particularly appealing to collectors and investors alike.
Remember that while finding a pedigreed shipwreck coin would be extraordinary, even common 1857-S double eagles from circulation can represent a solid investment and a tangible piece of the California Gold Rush era. Happy hunting!
