 After a small issue at London based on this same type, the new Mercian ruler Coenwulf instituted a reform of the coinage leading to the new "tribrach" type.This non-portrait type used an obverse design modelled on the earlier coinage of Cynethryth, and despite its use of the central M (for "Merciorum") was adopted by Eadbearht, Eadwald and even by Beorhtric of Wessex, who struck a very rare coinage around this time.By 798 Coenwulf had regained Kent and East Anglia also came back under his power by the 9th century.
