An archaeological excavation in Senon, a small village in the Meuse department of northeastern France, has uncovered a remarkable find: 40,000 Roman coins dating from 280 to 310 AD. The discovery was made by INRAP, the National Institute for Preventive Archaeological Research, during a routine excavation. The coins were found inside three ceramic containers known as amphorae, which were commonly used in ancient times for storing liquids or goods. Two of the amphorae contained large quantities—between 23,000 to 24,000 and 18,000 to 19,000 coins, respectively—while the third held only three coins. This uneven distribution suggests that the coins may have been accessed repeatedly over time, potentially indicating that the coins were being used or added to gradually, perhaps as a family savings plan rather than being hidden in a single emergency event. The site where the coins were discovered is located just 150 meters from a known military fortification, prompting researchers to consider whether the local population’s financial activities might have been influenced by the presence of Roman troops stationed nearby. Such proximity could have meant that the residents of Senon had a direct connection to the Roman military economy, whether through trade, taxation, or other interactions. The location also raises questions about the economic role Senon may have played in the region during the Roman era. Senon has a rich and complex history that predates the Roman conquest. It was once a major settlement of the Mediomatrici, a Celtic tribe that inhabited the area before the Romans arrived. Archaeological evidence suggests that the village may have been founded before the Roman period and experienced two fires, followed by reconstruction efforts beginning in the early 4th century. This history indicates that Senon was a place of significance long before the arrival of Roman influence. The discovery of the 40,000 coins adds a new layer to the understanding of Senon’s past, emphasizing its role as a historically important site. The presence of such a large number of Roman coins, along with the unique way they were stored, offers valuable insights into the economic habits of the people who lived there. It also highlights how the village has been a focal point of human activity for centuries, from the Celtic era through the Roman period and beyond.
