 Uniquely in Anglo-Saxon England, coins were also struck at Canterbury in the name of the queen, Cynethryth, from dies produced by the same talented individual responsible for the best of Offa's portrait dies.This practice could have been inspired by encounters with Roman coins in the names of empresses.It is also possible, though less likely, that the appearance of Irene on Byzantine coinage led Offa's queen to place her image on coins as well.
