Imagine spending sixty years quietly sitting in the earth, only to emerge as one of the most remarkable treasures in numismatic history. No, this isn’t the plot of a heist film—it’s the true story of the Traveller Collection, the largest and, arguably, one of the most adventurous coin collections ever amassed.
The Secret Life of 15,000 Coins
The Traveller Collection isn’t just vast; it numbers an astonishing 15,000 coins, making it the most expensive coin collection ever assembled. Its breadth is so staggering that it is being auctioned off in 15 separate sales stretched over three years. Yet, its sheer scale is matched by a Hollywood-worthy backstory: the entire collection was buried for fifty years, hidden away in cigar boxes to safeguard against looting during the chaos of World War II. Only in the 1990s did the coins finally see daylight again, much to the delight of collectors worldwide.
The Golden Star: A Ducat Worth Millions
This fall’s standout star from the collection is a 100 ducat gold coin, minted in 1629 by Ferdinand III of Habsburg. Estimated at CHF 2 million ($2.52 million), this coin isn’t your average piece of pocket change. Weighing an impressive 348.5 grams, it ranks among the largest gold coins of historic times. The coin pictures the Archduke of Austria in shining armor and a honeycomb ruff—back in the day, not quite Instagram-ready, but definitely awe-inspiring.
This glittering marvel was intended as a diplomatic gift for German princes during the Thirty Years’ War. Gifting coins to politically significant people was standard fare in the early modern era, and, as cataloguer Christian Stoess notes, “The weight of the gift coins was chosen according to the importance of the recipient and 100 ducats was the highest denomination.” In other words, if you got one of these, you’d made it—or at the very least, greatly impressed a Habsburg.

But that’s not all. There’s also a 100 ducat coin issued by Polish king Sigismund III in the 1620s, estimated at CHF 350,000 ($440,000). Minted to immortalize victory over the Ottomans in the Battles of Khotyn, a similar coin fetched $2.2 million in 2021, setting a Polish record. Adding to the commemorative parade is a medal depicting the future Polish king John III Sobieski, also marking the same battle, and tagged with a CHF 75,000 ($95,000) estimate.
A Journey Through Time, Wealth and War
The origins of the Traveller Collection are rooted in financial caution. After the Wall Street crash in 1929, the heir to a European family business decided coins were a safer bet than the stock market. Embarking on a globe-trotting quest for rarities, he and his wife scooped up treasures across Europe and the Americas throughout the 1930s. Economic turbulence brought opportunity: storied collectors like Waldo Newcomer and Philipp Ferrari de La Renotière were forced to sell their most remarkable coins, which the Traveller snapped up. According to Stoess, “A number of pieces in the collection come from the sales of both of these major collections,” while the absence of strong competition opened an unusually rich hunting ground for rarities during the Great Depression.
But then came World War II. Fearing theft or confiscation, the collector bundled his gold and silver coins into cigar boxes and buried them in his garden. The secret was kept between him and his wife until the mid-1990s—talk about long-term storage solutions. Today, the collection is insured for over $100 million, though the current inheritor prefers the anonymity of the shadows rather than the limelight.
Auction Fever: Rarity, Record-Setters, and Reawakening
Zurich-based Numismatica Ars Classica is managing the dispersal of the Traveller Collection, breaking it up into themed auctions. The first sale, devoted to British coins, already set pulses racing this May, pulling in CHF 6.3 million ($7.9 million) and more than doubling its presale estimate. The crown jewel? An 1839 £5 gold coin picturing a youthful Queen Victoria with a lion, sold for CHF 980,000 ($1.2 million)—one of just eight British coins to ever fetch over $1 million at auction.
Coming up in November, it’s Central Europe’s turn. Coins from this region, the bedrock of the collection, include gems that haven’t seen the auction block in over a century. The auction house is modestly anticipating CHF 5 million ($6.3 million) from this event alone.
- Featured coins from Poland, Germany, and Austria
- Portugal ösers from 16th-century Hamburg, with a 10 ducat coin expected to reach CHF 75,000 ($95,000)
- Most Hamburg Portugal ösers were commemoratives, minted from a single die pair, with fewer than 10 surviving
So, whether you’re a veteran collector or someone who once lost a penny in the couch, the saga of the Traveller Collection is a timeless reminder: history, wealth, and adventure may be closer—sometimes underground—than you think. Happy hunting (or digging)!
