The article describes the finds of six Roman coins and a mysterious object with an Arabic legend discovered in the years 2000–2014 at the bottom of Lake Turawskie, created in 1939. With the creation of the reservoir many archaeological sites (of varied chronology, from the Roman period to the late Middle Ages) were flooded, many of which could not be properly investigated due to the time pressure. The Roman coins presented here are a standard part in the overall image of coins discovered in Silesia. The mysterious object with an Arabic legend is unique, it has partial analogies in Norman weights or early-Arab coins (al-wafā lillāh coinage).
