 Towards the end of Æthelstan's reign and in the time of his successors Edmund, Eadred, Eadwig and the first part of Edgar's reign, the coinage was of a regionalised character, with up to seven regions of monetary circulation.The structure of this system is clearest for northern England thanks to the discovery of more numerous hoards in that part of the country.Coins normally stayed within their area of production, and different types were current in each region.
