ABSTRACT
Mark Blackburn had a prolic output across many areas of numismatics, but one in which he made a particularly important contribution was that of Viking coins and currency. is was a subject that he had addressed throughout his career, and especially the nal decade or so of his life.1 His detailed work on AngloScandinavian coinage began with the 1984 hoard from Ashdon, Essex, and continued with studies of the hoard from urcaston, Leicestershire, and the important productive site of the Viking winter camp at Torksey, Lincolnshire. ese were followed by surveys of Anglo-Scandinavian coinage both north and south of the Humber, and Mark chose the subject of Currency under the Vikings for the series of ve Presidential Addresses which he delivered to the British Numismatic Society in 2004-8. Viking Coinage and Currency in the British Isles was also the subject of his nal book, which reprinted the Presidential Addresses and eight other articles, with added comments and updates where appropriate, together with a major new article on the major Viking site at Torksey.2 is might suggest that there is little value in reviewing the state of the subject again so soon. However, a number of factors contribute to a developing understanding of the subject.
