An amateur archaeologist in Germany has uncovered the largest hoard of Roman coins ever found in the country from the reign of Emperor Hadrian. Oliver Riedl discovered the treasure near Wesseling, south of Cologne, after his metal detector signaled repeatedly, prompting him to notify authorities.

Experts who examined the site found a cache of 934 silver denarii, weighing a total of 3.1 kilograms (6.8 pounds). The coins are believed to have been buried during the second quarter of the second century AD. The find was unveiled at the LVR-LandesMuseum in Bonn, where it is now on public display.

Officials from the LVR Office for the Preservation of Archaeological Monuments in the Rhineland said the hoard’s owner likely buried the coins to keep them safe at a time when banking systems did not exist. Erich Classen, the office’s director, suggested that the individual may have died before retrieving or passing on knowledge of the treasure’s location, explaining why it remained hidden for centuries.

The precise value of the coins at the time of burial is difficult to determine, but researchers used the documented wages of Roman legionaries as a point of reference. Rahel Otte, a research associate involved in studying the hoard, explained that a typical soldier earned about 300 denarii annually, though roughly half of that was deducted for food and equipment. Consequently, it would have taken around six years for a legionary to save an amount equivalent to the hoard’s value.

This significant archaeological discovery offers new insights into the economic history of the Roman era in the region and illustrates the lengths individuals went to safeguard their wealth during a period lacking formal financial institutions.
