An extraordinary hoard of rare gold coins totalling 160 million coins or the so-called Traveller Collection has been discovered in Europe after being buried in the ground more than 50 years to hide it against Nazi treasure hunters during World War II. This hoard comprises 15,000 ultra-rare objects of over 100 inscriptions, and is the most valuable numismatic collection of its type to be auctioned as a block at once, starting November 6, 2025, at Numismatica Ars Classica (NAC) in Zurich.
The WWII-Era Burial Story
– The Traveller and his wife were acquired by a European collector in the 1930s after the Wall Street Crash, and they spent the following years of their life traveling across Europe/Americas and purchasing coins of historically important value, carefully recording every purchase.
– When the Nazi invasion was imminent, the collector buried the hoard in cigar boxes/aluminum cylinders on his grounds instead of being discovered and was instead killed shortly after (the place of discovery has remained unknown over the decades).
– It was found in the 1990s by Heirs and placed in bank strong-rooms, prior to NAC confirming/conserving the collection to go to auction- first British coins May 2025, Central Europe November 6.
