An amateur archaeologist discovered 934 ancient Roman silver coins in a field near Wesseling, south of Cologne. The local office in charge of archaeological monuments stated on Tuesday, Sept. 22, 2026, that the collection is the largest hoard of silver denarii from the era of Emperor Hadrian ever found in Germany.
The discovery occurred approximately one year ago when Oliver Riedl used a metal detector to locate several coins. After the device continued to signal additional finds, Riedl contacted authorities, who dispatched a team of experts to conduct a formal excavation. The completed collection weighs 3.1 kilograms (6.8 pounds) and went on public display at the LVR-LandesMuseum Bonn on Tuesday.
Archaeologists from the LVR Office for the Preservation of Archaeological Monuments in the Rhineland believe the hoard was deliberately buried during the second quarter of the second century A.D. Erich Classen, state archaeologist and director of the office, said the coins were likely hidden for safety as banks did not exist at the time, though he noted it is unclear why the owner never returned for them.
The coins vary in age, with at least one dating back to 148 B.C. during the Roman Republic era. Research associate Rahel Otte noted that an ordinary legionary at the time earned 300 denarii annually, but half was typically withheld for food and equipment. Otte stated that a soldier would have needed to save all disposable income for approximately six years to accumulate a fortune of this size.
The LVR Office for the Preservation of Archaeological Monuments in the Rhineland identified the find as the largest of its kind in Germany specifically from the reign of Hadrian, who ruled from A.D. 117 to 138. The hoard represents 934 silver denarii, illustrating the wealth concentration of a single unknown individual 1,900 years ago.
For an ordinary person, the scale of this find is best understood through the reported purchasing power of the era. A Roman soldier would have received a net disposable income of 150 denarii per year after deductions. To amass the 934 coins found in this field, that worker would have had to save their take-home pay for roughly six years. This provides researchers with evidence of the value placed on silver currency at a time when the Cologne region served as a military outpost for the Roman Empire.
Riedl followed protocols by alerting the state after his discovery. This allowed the LVR-LandesMuseum Bonn to preserve the site's context and eventually place the 3.1-kilogram collection on public display starting Sept. 22, 2026. While the coins are now in a museum, the identity of the original owner remains unknown, and experts say they can only speculate on whether the individual died before they could retrieve their savings.
