The dating of the earliest Anglo-Saxon coins is problematic since the design are all copied from existing coinage, Merovingian or Frisian. However, since both these sources have been extensively studied, it is possible to determine a terminus post quem for the source of the design, and therefore an approximate start-date for the issuance of the coin-type. These first, derivative coin types are known as the 'primary series'. They are are generally of good metal quality and weight (ca. 1-1.3 grams) and largely restricted to circulation in Kent and the Thames Estuary, from a probable source in the vicinity of the Kentish royal court at Canterbury. A few early sceats were also produced in Northumbria, bearing the name of King Aldfrith (685-704 A.D.), who came to the throne after the death of his elder brother, Ecgfrith, in battle at Nechtansmere.
