More than 40,000 Roman coins, divided into three separate deposits, were recently uncovered in three neighboring houses in Senon, a town located in the Meuse region, about 20 kilometers from Verdun. The discovery was made during a preventive archaeology operation, triggered by a planned house extension. Conducted by the National Institute for Preventive Archaeological Research (Inrap), the dig covered a 1,500 square meter area, revealing an entire neighborhood of an ancient settlement. These excavations, completed in November 2025, uncovered three large monetary deposits of remarkable size, offering a rare glimpse into daily life in the Roman era. The area excavated corresponds to the urban center of ancient Senon, a major city of the Mediomatrici, a Gallic tribe whose capital was Metz. The site, known since the 19th century, is near a public square that once housed temples and a theater. The settlement, likely home to several thousand people, also featured thermal baths. Archaeologists found two paved streets lined with at least three houses. The well-preserved structures include living rooms with lime concrete floors or hypocaust heating systems, cellars accessed by limestone steps, and private gardens, offering insight into the domestic life of the time. The initial discovery of a few ancient coins by an amateur diver led to the unearthing of more than 30,000 bronze coins from the 4th century, found near the coast of Sardinia. These coins are a reminder of the maritime activity during the time of the Western Roman Empire. The presence of ceramic fragments and tools like metal knives and bone pins suggests the inhabitants were merchants and artisans who had accumulated significant wealth. Other finds include everyday objects such as Gallo-Roman ceramics, metal knives, and clothing fasteners like brooches and pins. Three deposits, each containing several thousand coins stored in large ceramic vessels, were found in different houses within the same neighborhood. These vessels, typically used for storing liquids, were buried in pits inside the homes and surrounded by stone blocks. Vincent Geneviève, a numismatist at Inrap, estimates the total number of coins to be over 40,000, though the exact number is still being determined. The coins date from the last quarter of the 3rd century to the first decade of the 4th century, a time of economic instability in the Roman Empire. Some of the coins are counterfeit, and others feature the image of Emperor Claudius II, minted after his death. Archaeologists avoid using the term "treasure" to describe these deposits, emphasizing that such accumulations could result from various motivations, not just hoarding. The three deposits are located in three separate houses, approximately 50 meters apart. They contain different types of coins, and there is no indication of a hurried concealment. The vessels were carefully placed in pits within living areas, suggesting they were used for regular access. Simon Ritz, the scientific director of the excavation, notes the shallow depth of the pits, which may have allowed for easy retrieval of coins. The preferred explanation is that these were part of an active domestic financial management system, rather than a response to sudden danger. The significance of this site lies not only in the number of coins but in the context in which they were found. While monetary deposits are common in the Meuse region—more than thirty have been recorded since the 18th century—this discovery is unique because it allows researchers to study the coins in their original archaeological setting. The ceramic vessels have helped preserve the coins from corrosion, allowing for clear readings of imperial portraits. A two-year post-excavation study is expected to analyze the relationships between the three deposits and their possible functions. The timing of the deposits coincides with a Roman military presence in the region, raising questions about a potential connection. However, the settlement was eventually abandoned during late antiquity, following a series of fires.
