 The only substantial hoard of English coins from this period was found at Crondall, and included 69 English "tremisses" as well as a number of Frankish "tremisses", probably deposited around 630.These and other finds reveal a range of types that rarely name a mint or issuing authority, though one scarce type bears the name of London, and others are struck in the name of King Eadbald of Kent (616–40).In terms of design they are based on Roman and Merovingian prototypes.
