Penny - Ecgberht Rochester mint

Ecgberht's consolidation of Anglo-Saxon England is well documented, but his Rochester mint output occupies a peculiar position in that story. Rochester — a Kentish mint with deep Mercian associations — came under Ecgberht's control only after his decisive defeat of Beornwulf of Mercia at Ellandun in 825, which effectively ended Mercian dominance over the southeast. Pennies from Rochester under Ecgberht therefore cannot predate that conquest, compressing the actual production window considerably despite the reign dates spanning 802–839.

North 576 is notably scarcer than the Canterbury issues of the same reign.
