The $100 Million Traveller Collection: A Buried Coin Hoard That Survived War and Time

2025

Coins have been part of human life since the first Croesus staters appeared in ancient Lydia in the sixth century BC. Over the centuries, nations have minted coins to honor leaders, victories, beliefs, and turning points in history. With so many designs and stories pressed into metal, it was inevitable that coin collecting would grow into a global passion.

On May 20, one of the most extraordinary private collections ever assembled will go to auction in Zürich. Known as the Traveller Collection, it is expected to bring in more than $100 million. Its arrival on the market comes with a story that sounds almost cinematic: a treasure buried for more than half a century, hidden from war, forgotten by time, and rediscovered only because of one man’s meticulous notes.

The Traveller Collection began with an anonymous European collector living in the 1930s. After the 1929 stock market crash, he turned his attention to coins, selecting pieces from different eras and countries with a careful eye for quality. As he traveled across Europe and the Americas with his wife, the collection grew to 15,000 coins, each one documented in his notebook with precision.

Around 1940, as Nazi forces advanced, he packed the coins into aluminum boxes and buried them. He never lived to see his country liberated. But his notes survived, and decades later his heirs used them to locate the buried boxes. After more than fifty years underground, the coins were moved to a bank vault and eventually to Numismatica Ars Classica, where they will soon be offered to the world.

Stories like this weren’t uncommon in that era. In the Czech Republic, hikers recently uncovered a stash of 600 gold coins buried during the same period, likely hidden from the Nazis. Turmoil forces people to protect what they can, and sometimes those protections become time capsules.

Among the Traveller Collection’s standout pieces is a 100‑ducat gold coin minted in 1629 under Ferdinand III of the Habsburg Dynasty. Coins of this type haven’t appeared at auction since World War II, making it one of the rarest offerings in the sale. Ferdinand III ruled as Archduke of Austria and King of Hungary before becoming Holy Roman Emperor in 1637. His family ties stretch back to Charles V, whose rise to power was backed by Jakob Fugger, the wealthiest man in recorded history. During Ferdinand’s era, the Fugger family was minting ducats of their own, adding another layer of historical weight to the coin.

The Traveller Collection reaches far beyond Europe. It includes gold tomans from Iran’s Qajar dynasty, minted under Agha Mohammad Khan Qajar in the late eighteenth and early nineteenth centuries. The toman, originally valued at 10,000 dinars, reflects a monetary system very different from the Western world. Another unusual piece is the 1853 Port Philip coin from Australia, an early attempt at a national currency that features a kangaroo on its face. Numismatica Ars Classica has emphasized the rarity of these coins, noting that several have never appeared in a public auction and many are preserved in a condition almost never seen today.

The oldest coin in the collection carries a story worthy of ancient drama. It is an Athenian gold stater struck in 296 BC, bearing Athena on one side and her owl on the other. This particular coin was minted during the rule of Lachares, a demagogue who seized control of Athens and declared himself tyrant. According to the writer Pausanias, Lachares funded his regime by stripping gold from the Temple of Athena on the Acropolis, even removing ornaments from the statue itself. Whether this stater was minted from that stolen gold is impossible to know, but the possibility adds a sharp edge to its history.

The Traveller Collection is more than a set of rare coins. It is a record of one man’s determination to preserve pieces of the world during a time when the world was tearing itself apart. As the collection heads to auction, those with the means to bid will have a chance to own artifacts that carry not only monetary value but the weight of human resilience, conflict, and survival.

SALES:

The Traveller Collection didn’t sell in one single event — it has been auctioned in multiple high‑profile sales by Numismatica Ars Classica (NAC), and the totals are spread across several auctions. Here are the confirmed sale figures from the sources:

The first Traveller Collection auction (May 2025) The initial sale focused on British coins and brought in £5.7 million, and with fees the total reached around £7 million.

The second Traveller Collection auction (also November 2025) Another report confirms the same 100‑Ducat “Gold Giant” sold for CHF 2,388,750, roughly $2,986,207 USD, making it the most expensive post‑antique European gold coin ever sold.

Later auctions (May 2026) Traveller Collection coins continued selling in NAC’s Auction 167 and 168, with many pieces reaching six‑figure prices. One highlight was a Great Britain 1826 Proof Set that sold for 588,000 CHF (about $747,000 USD).

• Hundreds of thousands to millions for numerous individual coins in 2025–2026 auctions

The full collection is expected to exceed $100 million USD once all auctions are complete — and based on the results so far, it’s on track to do exactly that.
