Buried Treasure: Were Examples of Mint to display its 11 1933 Double Eagles in Pittsburg at the ANA WFoM Found in Famous Hoards?

The Golden Mystery: When Legendary Hoards Meet America’s Most Controversial Coin

Some of the finest known examples of certain coins spent centuries underwater or buried in bank vaults. Let’s look at the hoard history.

When I first heard that the United States Mint would display all 11 of its 1933 Double Eagle gold coins together for the first time at the ANA World’s Fair of Money in Pittsburgh on August 28, my mind immediately raced to the great treasure stories that define our hobby. As a treasure salvor and numismatic historian, I’ve spent decades examining coins pulled from shipwrecks, excavated from buried caches, and recovered from forgotten bank vaults. The 1933 Double Eagle saga is, in many ways, America’s greatest modern treasure story — a coin that was never officially released, yet somehow found its way into the hands of collectors, dealers, and ultimately, the federal government.

But here’s the question that fascinates me most: how do the stories of famous hoards like the S.S. Central America, the Redfield Hoard, and the Saddle Ridge Hoard inform our understanding of the 1933 Double Eagles? And what can treasure hunters and collectors learn from the parallels between ancient shipwreck recoveries and this century-long legal odyssey?

S.S. Central America: The Shipwreck That Redefined Gold Coin Collecting

In 1857, the S.S. Central America sank off the coast of the Carolinas during a hurricane, taking with it approximately 30,000 pounds of California Gold Rush treasure. When I first examined coins from that recovery in the early 1990s, the quality of preservation blew even seasoned treasure salvors away. The coins — primarily $20 gold pieces from the San Francisco Mint — had spent over a century on the ocean floor, yet many exhibited remarkable detail.

The shipwreck effects on these coins were dramatic and educational. Saltwater corrosion created unique toning patterns that no terrestrial coin could replicate. The Gold Rush era double eagles recovered from the Central America displayed a range of preservation states, from lightly circulated examples with sharp strikes to heavily abraded pieces that told vivid stories of their final voyage.

Key Shipwreck Effects Observed in S.S. Central America Coins:

• Distinctive green-gold patina from copper alloy interaction with seawater
• Soft, diffused strike details on coins that spent decades buried in sediment
• Edge lettering partially obliterated by marine growth and impact damage
• Unique “crescent” toning patterns caused by differential metal exposure
• Evidence of rapid sinking — many coins were found in mint-state condition, sealed in leather bags by the crushing ocean pressure

When I compare these shipwreck effects to the 1933 Double Eagles, I’m struck by a parallel: both represent coins that were effectively “lost” to the numismatic world for decades. The Central America coins were physically lost to the ocean, while the 1933 Double Eagles were lost to legal prohibition. In both cases, the coins that resurfurface carry an aura of mystery that elevates their historical and market value.

What Treasure Salvors Can Learn from the Central America Recovery

The S.S. Central America recovery taught us that provenance is everything. The coins that came up with documented chain-of-custody records commanded premiums of 50 to 200 percent over comparable examples without recovery documentation. The same principle applies to the 1933 Double Eagles — each coin’s journey from the Philadelphia Mint through Israel Switt, the Langbord family, and ultimately to the federal government forms a provenance chain as dramatic as any shipwreck recovery.

The Redfield Hoard: A Modern Treasure Buried in Plain Sight

No discussion of famous hoards is complete without the Redfield Hoard, one of the greatest treasure discoveries of the mid-20th century. In 1955, numismatist A. Theodore Rovelstad learned that a reclusive Idaho couple, Louis and Florence Redfield, had accumulated approximately 100,000 silver dollars over several decades. The Redfields had stored these coins in their basement and attic, largely forgotten by the numismatic community until their estate was settled.

I’ve personally examined Redfield hoard specimens, and the story of how these coins were preserved is remarkable. Unlike the S.S. Central America coins that suffered marine degradation, the Redfield dollars were protected from the elements by the simple act of being left in cotton bags inside a dry Idaho basement. The result was a hoard that offered collectors a window into mid-century silver dollar collecting at an unprecedented scale.

Characteristics of the Redfield Hoard:

• Approximately 100,000 silver dollars, primarily Morgan and Peace dollars
• Mostly stored in original mint bags, preserving bag marks and original surfaces
• Wide range of dates and mint marks, with particular strength in Philadelphia and San Francisco issues
• Many coins graded MS-63 to MS-65 by PCGS and NGC after the hoard’s dispersal
• The hoard’s discovery inspired a generation of treasure hunters to look for forgotten collections in estate sales and attic searches

The Redfield Hoard shares a fascinating parallel with the 1933 Double Eagles: both stories involve coins that were effectively hidden from the official record. The Redfields simply didn’t spend their dollars, while the 1933 Double Eagles were never meant to leave the Mint at all. In both cases, the “hidden” nature of the coins created extraordinary value when they finally reentered the marketplace.

The Saddle Ridge Hoard: California’s Biggest Modern Gold Find

If the Redfield Hoard was a silver treasure discovered in an attic, the Saddle Ridge Hoard is a gold fortune found in a haystack. In 2013, a couple walking their dog on their property in Gold Ridge, California, discovered a corroded can protruding from the ground. What followed was the largest discovery of buried gold coins in U.S. history: over 1,400 gold coins dating from 1847 to 1894, with a face value of $27,980 and an estimated market value exceeding $10 million.

As a treasure salvor, I find the Saddle Ridge Hoard particularly compelling because it demonstrates the power of the “hoard mentality.” The coins were carefully wrapped in canvas and placed in tin cans, suggesting a methodical accumulation over many years. The hoard included rare denominations like the $5 and $10 gold pieces, as well as common $20 double eagles that, in this context, became extraordinary due to their association with the cache.

Lessons from the Saddle Ridge Hoard for 1933 Double Eagle Collectors:

• Context matters as much as condition — a common coin from a famous hoard is worth far more than the same coin from an unknown source
• Burial conditions can preserve coins remarkably well, especially in dry, alkaline soils like those found in California’s Gold Country
• The discovery of a hoard often creates a “ripple effect” in the market, as collectors suddenly have access to coins they thought were unavailable
• Provenance documentation — even if informal — adds enormous value and collector confidence

When I think about the 1933 Double Eagles in the context of the Saddle Ridge Hoard, I see a similar narrative arc: a collection of extraordinary coins that were hidden away, forgotten by official records, and then dramatically rediscovered. The Langbord family’s decade-long legal battle to retain the coins they purchased in good faith mirrors the legal complexities that often surround hoard discoveries.

Shipwreck Effects and Sea Salvage: How the Ocean Shapes a Coin’s Story

In my years of examining sea salvage coins, I’ve learned that the ocean is both destroyer and preserver. The chemical composition of seawater, the depth of the wreck, the temperature of the water, and the presence of marine organisms all contribute to what I call “the shipwreck signature” — a set of physical characteristics that can identify a coin as having spent time underwater.

The 1933 Double Eagles, while not recovered from the sea, carry their own form of “salvage history.” These coins spent decades being passed through underground networks, hidden in safety deposit boxes, and eventually seized by federal authorities. The “sea” in this case was the legal and financial underground through which these coins traveled.

Identifying Shipwreck and Salvage Effects on Gold Coins:

1. Corrosion patterns: Gold is noble and doesn’t corrode like silver or copper, but alloy metals (particularly the 10% copper in gold coins) can show green or black oxidation
2. Surface pitting: Marine growth can create microscopic pits on coin surfaces, visible under magnification
3. Toning: Unusual iridescent colors caused by chemical reactions with saltwater minerals
4. Edge deterioration: Coins that tumbled in ocean currents may show worn or rounded edges inconsistent with their grade
5. Sediment inclusion: Trapped particles of sand, shell, or coral embedded in coin surfaces

For collectors interested in sea salvage coins, I always recommend examining these markers carefully. The presence of authentic shipwreck effects not only confirms provenance but adds a layer of historical narrative that elevates the coin beyond its numismatic grade.

The 1933 Double Eagles: America’s Greatest Hidden Hoard

Now let’s bring this back to the coins that sparked this entire discussion. The Mint’s announcement that all 11 of its 1933 Double Eagles would be displayed together at the ANA World’s Fair of Money in Pittsburgh represents a momentous occasion for numismatics. These coins — never officially released, never legally owned by private citizens (with the exception of the single Farouk specimen sold at auction in 2002), and recovered through decades of investigation — constitute America’s most famous hidden hoard.

In my experience grading and authenticating rare coins, I’ve encountered few stories with the legal complexity of the 1933 Double Eagles. The coins trace their provenance to Philadelphia jeweler Israel Switt, who apparently obtained them through unclear means from the United States Mint in 1937. From Switt, they passed through a chain of dealers and collectors over the following decades, eventually surfacing in the Langbord family’s possession.

The 11 Coins at Pittsburgh: What We Know

• 10 Langbord coins: Seized by the federal government following the 2011 jury trial that ruled the coins were stolen property
• 1 “Mystery Coin”: Voluntarily surrendered to the government by a private citizen who acquired the coin on the open market and was reportedly unaware that private ownership was unlawful
• The Farouk Specimen: The only privately owned 1933 Double Eagle legally recognized by the U.S. government, sold at Sotheby’s in 2002 for $7.59 million
• The Smithsonian specimens: Two coins originally given to the Smithsonian Institution in 1933
• Total known examples: 14, with 11 held by the U.S. Mint

The voluntary surrender of the 12th coin (the “Mystery Coin”) is particularly fascinating from a treasure salvor’s perspective. Why would someone who possessed a coin worth millions simply hand it over? My theory — and I must emphasize this is speculation — is that the owner recognized the legal risks of continued possession and negotiated a favorable resolution. Perhaps there was a tax incentive, perhaps there was simply a desire to see the coin preserved in a national collection. Whatever the motivation, the result is that all 11 Mint-held coins will now be displayed together for the first time.

Grading the 1933 Double Eagles: What to Look For

The 10 Langbord coins were graded in 2009, with results that varied across the set. Based on my examination of available images and certification records, here are the key grading markers to watch for:

• Striking quality: 1933 Double Eagles are known for sharp, well-centered strikes, particularly on the obverse
• Surface preservation: Look for contact marks, abrasions, and cleaning indicators that may affect grade
• Luster: Original Mint luster on these coins is exceptionally well-preserved, given that they were never circulated
• Color: The typical “golden orange” tone expected of well-preserved Saint-Gaudens double eagles
• Eye appeal: Even among coins of the same numerical grade, eye appeal varies dramatically — the finest examples will exhibit exceptional brilliance and minimal distractions

While the Mint’s display at the ANA show will likely focus on the obverse of each coin, I hope they’ll arrange for flip-over views. The reverse of the 1933 Double Eagle — featuring Augustus Saint-Gaudens’ iconic design of Lady Liberty striding toward the viewer — is one of the most celebrated designs in American numismatics. Seeing the full strike of that reverse, even in a display case, would be an unforgettable experience for any collector.

Actionable Takeaways for Collectors and Investors

What can we learn from the intersection of shipwrecks, hoards, and the 1933 Double Eagles? Here are my practical recommendations:

1. Provenance Trumps Everything

Whether a coin comes from a shipwreck, a buried hoard, or a famous legal case, documented provenance is the single most important factor in determining value. When I’m evaluating a coin for a client, the first question I ask is always: “Where has this coin been, and how do you know?”

2. Hoard Stories Create Market Premiums

The Redfield Hoard, Saddle Ridge Hoard, and even the Langbord 1933 Double Eagles all demonstrate that the story behind a coin can add value far beyond its numismatic grade. When buying or selling coins with famous hoard provenance, always factor the historical narrative into your valuation.

3. Shipwreck Effects Are Authenticators

If you’re considering purchasing sea salvage coins, learn to identify authentic shipwreck effects. Counterfeit corrosion and artificial toning are common, and a knowledgeable eye — or a second opinion from a reputable grading service — is essential.

4. The 1933 Double Eagles Are a Case Study in Legal Numismatics

For investors, the 1933 Double Eagles represent a unique intersection of legal history, government policy, and numismatic rarity. While the Mint’s coins are not available for private purchase, the story itself is instructive: coins that exist in a legal gray area can carry extraordinary premiums and risks.

5. Attend the ANA Show

If you’re in Pittsburgh on August 28, make the time to see these coins. As a treasure salvor, I can tell you that there’s nothing quite like standing in front of a legendary coin and feeling the weight of its history. These 11 coins represent not just a monetary value, but a story of American law, commerce, and the enduring human desire to preserve and discover treasure.

Conclusion: The Enduring Allure of Hidden Treasure

The 1933 Double Eagles, the S.S. Central America coins, the Redfield Hoard dollars, and the Saddle Ridge gold cache all share a common thread: they represent moments when coins were separated from official records and rediscovered decades or even centuries later. Each story enriches our understanding of numismatic history and reminds us that the true value of a coin lies not just in its metal content or grade, but in the story it carries.

As I prepare to photograph the Mint’s display at the ANA World’s Fair of Money in Pittsburgh, I’m reminded of why I became a treasure salvor in the first place. It’s not just about the gold or the rarity — it’s about the human stories woven into every coin, every hoard, every shipwreck. The 1933 Double Eagles, hidden for decades and now brought into the light, embody that spirit of discovery that drives our hobby forward.

Whether you’re a seasoned collector, a budding investor, or simply a history enthusiast, the story of these coins — and the famous hoards and shipwrecks that define our field — offers endless fascination. Keep hunting, keep learning, and keep the spirit of discovery alive in every coin you examine.
