Three coins were found during a small archaeological excavation at the medieval castle in the Lower Silesian village of Stare Kolnie (Popielów Commune, Opole County, Opolskie Voivodeship): a Silesian kwartnik from the beginning of the 14th century, a Wrocław heller from the years 1417-20 and a counterfeit Polish half-groschen struck after 1410. The kwartnik belongs to the oldest artifacts found at the castle, whereas the fifteenth-century coins were found in the layer related to the final demolition of the castle during the fighing in 1443.
