During excavations in the village of Senon, a team from the National Institute for Preventive Archaeological Research (INRAP) found three amphorae buried beneath the floor of an ancient residence.

Together, the vessels may have originally held over 40,000 coins. The first jar contained approximately 38 kilograms of coins (roughly 24,000 pieces), while a second weighed 50 kilograms (holding an estimated 19,000 pieces). A third vessel had been emptied in antiquity, with only traces remaining, Live Science reports.

The coins date between AD 280 and 310, depicting emperors of the breakaway Gallic Empire. Unlike typical hoards buried hastily during times of conflict, these jars were carefully sunk into the living room floor with their rims accessible at ground level. This suggests the owners utilised them for long-term savings rather than emergency concealment. A massive fire eventually destroyed the settlement in the fourth century, leaving the wealth untouched for nearly two millennia.
