The Eureka Gold Bar
The World’s Most Valuable Gold Rush Artifact – A Priceless Piece of American History
About The Legend
A monetary document made of gold
The Eureka Bar is not just gold – it’s a monetary instrument, a financial document of 1857 California, stamped with its exact value and used for large commercial transactions.
Hand-poured by the prestigious firm of Kellogg & Humbert in San Francisco, this 64-pound nugget was destined for the Philadelphia Mint to be turned into coins to fuel America’s rapidly expanding pre-Civil War economy.
It only exists today because of a tragedy. The SS Central America sank in a hurricane on September 12, 1857, carrying 7,200 feet beneath the ocean for 131 years.

Its Journey Through Time
From the Gold Rush to Kagin’s Digital Community

1857
The Birth of a Legend
In the spring and summer of 1852 at 108 Montgomery Street in San Francisco, the prestigious assay firm of Kellogg & Humbert poured an extraordinary gold nugget that would become the stuff of legend.
The Eureka Bar was designed for the Philadelphia Mint, where it would have been melted down and turned into coins to fuel America’s rapidly expanding pre-Civil War economy. In the fall of 1857, it went aboard the SS Central America.

Sept. 12th, 1857
Tragedy Strikes
The SS Central America—a 280-foot sidewheel steamer—had departed from San Francisco on September 3, 1857, carrying 577 ounces and over 3 tons of California gold. Passengers included successful miners, entrepreneurs, and businessmen.
On September 9 the vessel encountered a Category 2 hurricane off the Carolinas. At 8:00 PM, September 12, 1857, the SS Central America succumbed to the storm and plunged to the ocean floor—7,200 feet beneath the Atlantic.

Sept. 11th, 1988
The Discovery
After years of research and raising $12.5 million, marine engineer Tommy Thompson assembled a team to attempt the impossible: finding the SS Central America wreck, 7,200 feet below the Atlantic.
Using a revolutionary underwater robot named “Nemo” equipped with cameras and robotic manipulators, Thompson’s team made the discovery on September 11, 1988—exactly 131 years and one day after the sinking.

Record Sale
After years of legal battles and conservation work, the Eureka bar shattered the numismatic world record in 2001. Sold for a record-setting price, this piece crushed all previous records.
Declared a national treasure by experts, the bar vanished into a private collection where it would remain hidden from public view for over two decades.

Jun. 2023
A National Treasure Reemerges
After 21 years of absence, the impossible happened—the Eureka Bar returned to public display at the Long Beach Coin, Currency, Stamp & Sports Collectible Expo in June 2023. Thousands of people stood in line to see it for the first time in a generation.
Adam Crum compared the experience to viewing the Hope Diamond at the Smithsonian. “There’s standing in line to look at this Hope Diamond. It’s the only thing that I’ve ever seen comparable to the Eureka Bar exhibit.”
