 These include a portrait coin – probably from around the same time as the London monogram pennies – with the mint-name ÆT GLEAPA ('from Gloucester'), which had become an important centre of 'English' Mercia under Alfred's ealdorman Æthelred; a small number of 'four-line' non-portrait pennies with reverse mint names assigning their production to Winchester and Exeter; another non-portrait series probably struck at Oxford (OHSNAFORDA); and large silver 'offering pieces' inscribed ELIMOSINA ('alms').Northumbria's numismatic history was quite distinct from that of the south.Coinage never petered out as completely as it did below the Humber, and until close to the end of its history Northumbrian coinage remained closely linked to the king and archbishop.
