 This coinage persisted until the conquest of East Anglia by Edward the Elder in 917/18.In Northumbria, the highly debased "styca" coinage came to an end and was replaced with a fine silver coinage, which is very well known thanks to the huge (c. 8,000 coin) Cuerdale hoard deposited in the first decade of the 10th century.Sometimes this coinage named local Viking rulers (the identification of whom with figures from written sources is often impossible or contentious) but, at the start of the 10th century, the name of the mint and that of Saint Peter replaced references to king and moneyer.
