Amateur archaeologist Oliver Riedl was using a metal detector in a field near Wesseling, south of Cologne, when the device began to signal continuously. Riedl reported the find, and a team of specialists later uncovered 934 Roman silver denarii, the largest hoard from the era of Emperor Hadrian ever discovered in Germany.
The coins, which weigh 3.1 kilograms (6.8 pounds), were displayed at the LVR‑Landesmuseum Bonn on Tuesday. Experts at the LVR Office for the Preservation of Archaeological Monuments in the Rhineland believe the silver was deliberately hidden during the second quarter of the second century AD.
State archaeologist Erich Classen said the motive was likely to keep the money safe, noting that banks did not exist at the time. He added that the hoard may have remained buried because its owner died before it could be retrieved. The rarity of such extensive second‑century finds makes it difficult to estimate the original value of the treasure.
Rahel Otte, a research associate at the office, explained that an ordinary legionary earned about 300 denarii a year, with roughly half withheld for food and equipment. To accumulate the Wesseling hoard, a soldier would have needed to save all disposable income for about six years, though the identity of the hoard’s owner remains unknown.
The region surrounding Cologne was part of the Roman Empire from roughly 39 BC to AD 459. Roman control was established under General Marcus Vipsanius Agrippa, who set up a military post along the Rhine that later evolved into Colonia Agrippina, the modern city of Cologne.
