 The last two phases of Æthelwulf's coinage were common to both Rochester and Canterbury, with dies for both mints in the final phase coming from a common source at Canterbury.The third type of Æthelwulf's reign was a non-portrait coinage with the ambiguous mint legend DORIBI (which could refer to either Canterbury, "Dorobernia"; or Rochester, "Dorobrebia") and a monogram for CANT("ia").Æthelwulf's last coinage was a new portrait type of very different style.
