Authorized detectorist’s alert leads archaeologists to 934 Roman denarii near Cologne

Oliver Riedl, searching legally near Wesseling south of Cologne, found 15 Roman silver denarii before calling in Germany’s LVR Office for Archaeological Heritage Management. Excavation yielded more than 934 denarii, nearly seven pounds of coinage about 1,900 years old from Emperor Hadrian’s reign, among the largest Roman hoards of its kind.
