$10 Million “Eureka” Gold Rush Bar Hits Market with Fractional Ownership Opportunity

Legendary SS Central America Treasure Returns to the Spotlight

A monumental artifact from the California Gold Rush has re-emerged. Moreover, it now comes with a modern twist.

For the first time, investors can purchase fractional ownership in the famed “Eureka Bar,” a massive 64-pound gold ingot recovered from the wreck of the SS Central America, the legendary “Ship of Gold.”

Kagin’s Digital, a subsidiary of Kagin’s Inc. based in Belvedere Tiburon, California, announced the offering on March 17, 2026. The firm has structured the historic bar into a digital investment vehicle designed for accredited investors.

A 933-Ounce Giant from the California Gold Rush

Forged in San Francisco in 1857, the Eureka Bar weighs an extraordinary 933.34 troy ounces. Augustus Humbert, a prominent assayer, and private coiner John Glover Kellogg produced the ingot during the height of the California Gold Rush.

Dr. Donald Kagin, President of Kagin’s Digital and author of Private and Pioneer Gold Coins of the United States 1786–1862, emphasized its importance:

The Eureka Bar ranks as the largest surviving gold artifact of the California Gold Rush. It also stands among the most historically significant gold bars ever produced.

Indeed, experts often describe the bar as a “monetary document made of gold.” It functioned not only as bullion but also as a financial instrument during a transformative period in American economic history.

The “Ship of Gold” and the Greatest Treasure Ever Found

The Eureka Bar lay lost for more than 130 years beneath the Atlantic Ocean.

The SS Central America sank in 1857 during a hurricane, carrying tons of California gold. As a result, the disaster contributed to the financial panic of that same year.

Recovery efforts began more than a century later. Between 1988 and 1990, the Columbus-America Discovery Group, led by treasure hunter Tommy Thompson, successfully salvaged a significant portion of the treasure. Later, Odyssey Marine Exploration conducted additional recovery in 2014.

Life magazine famously called the find the “Greatest Treasure Ever Found.” The recovered trove has an estimated value exceeding $100 million.

Furthermore, much of the treasure entered the market through the California Gold Marketing Group and Adam Crum of FinestKnown.com.

Record-Breaking Provenance and Value

The Eureka Bar has long commanded elite status among collectors.

In 2002, a private buyer acquired the ingot for $8,000,000 as part of a larger transaction involving additional gold bars and coins from the wreck. At the time, the sale set a record for a numismatic rarity.

Today, the bar carries an insurance valuation of $10,000,000.

Adam Crum, Managing Partner of National Treasures and a leading authority on the SS Central America treasure, underscored its significance:

The Eureka Bar stands alone. It is the largest California Gold Rush artifact and, in my view, the most important surviving gold bar in the world.

Fractional Ownership Opens a New Door

Now, Kagin’s Digital has introduced a new way to own a piece of this historic treasure.

The firm structured the Eureka Bar as a $6,500,000 digital fractional offering. It will issue 1,500 shares to members of its platform.

As a result, accredited investors can participate at an average share price of approximately $4,333.

Dr. Kagin explained the appeal clearly:

This structure allows individuals to participate in ownership of an incredibly important California Gold Rush artifact and iconic treasure.

Importantly, the offering complies with Rule 506(c) of Regulation D under the Securities Act of 1933. Therefore, only accredited investors may participate.

Blockchain Technology Secures Ownership

Kagin’s Digital has paired this historic asset with modern infrastructure.

Each fractional share is recorded using blockchain-based technology. Consequently, ownership records remain transparent, secure, and tamper-resistant.

This approach ensures efficient management of shares while preserving the provenance expected of a museum-grade artifact.

Why the Timing Matters

The announcement arrives amid renewed public attention on the SS Central America treasure.

Recently, treasure hunter Tommy Thompson returned to the spotlight following his release from prison. His original expedition team played a central role in recovering what many consider the most important numismatic treasure in American history.

Therefore, interest in the Eureka Bar, and the broader treasure, has surged once again.
