15,000 rare coins reappear in a World War II hiding place: the auction will take place on May 20, 2025

A couple’s incredible discovery is reshaping numismatic history and captivating enthusiasts worldwide.

A rediscovered coin hoard of 15,000 pieces, known as the Traveller Collection, has just been revealed to the public, sparking excitement across collector circles everywhere. Estimated at $160 million in value, this hidden fortune was buried decades ago to keep it safe from the reach of Nazi forces during World War II. After lying dormant for over 50 years, it is finally set to go under the hammer.

The origins of this remarkable treasure date back to the aftermath of the 1929 Wall Street Crash. A European collector and his wife roamed Europe and the Americas in search of precious coins, gathering a vast array of rarities. As conflict loomed, they chose to seal their prized pieces in aluminum containers and cigar boxes rather than risk losing them to approaching Nazi troops. Sadly, the collector passed away without divulging the exact site of the stash, leaving his wife as the sole guardian of this secret until it resurfaced.

Details behind the astonishing discovery of the Traveller Collection after 50 years

Experts say the coins span over 100 territories, featuring emblematic items like the 100 Ducat coin of Ferdinand III of Habsburg, minted in 1629. This behemoth weighs more than 300 grams of gold, making it one of the largest gold coins on record. But that’s only the tip of the iceberg: many of these pieces are from vanished empires or feature intricate details rarely seen today. Imagine stumbling upon such relics—wouldn’t you be tempted to peek inside those containers yourself?
