Germany's Largest Hadrian-Era Roman Coin Hoard Found Near Cologne

Germany's largest hoard of coins from Emperor Hadrian's reign — 934 silver denarii (standard Roman silver coins) — was found by private detectorist Oliver Riedl in a Wesseling field south of Cologne in autumn 2025. He alerted authorities quickly, allowing expert excavation. Archaeologists say it was likely buried on purpose in the second quarter of the second century AD.
