About AD 975/980, Harold Bluetooth, King of Denmark c.958-c.987, introduced the first nationwide coinage in Denmark. The iconography of the coins was clearly Christian with cross motifs, reflecting the King's conversion c.962/963. This coinage rapidly played a very important role in the currency as reflected in the composition of hoards from almost all parts of the country, from Northern and Western Jutland to Scania. This wide distribution confirms the statement on the King's great rune stone in Jelling, claiming that Harold won for himself all of Denmark. This book presents a detailed analysis of the coin hoards buried in Denmark and Scania during King Harold's reign, followed by a discussion of the coinage and its function in contemporary Denmark. Recent metal detector and excavation discoveries suggest that the Cross coins were struck in Haithabu, which must have been under firm Danish control throughout the period of production. In this thriving trading place, the coins were used by number in a managed currency, in contrast to the dominant weight economy (coins and other silver artifacts used at weight) in the rest of Denmark. Moreover, King Harold very likely used the coinage for payments to the magnates of his kingdom.
