Viking king of York, probably the same Sigeferth mentioned by the Anglo-Saxon Chronicle in the entry for 893: "Sigeferth the pirate arrived from the land of the Northumbrians with a large fleet, ravaged twice along the coast on that one expedition, and afterwards sailed back to his own land."

This coin was very probably part of the Cuerdale Hoard, thought to have been deposited between about 903 and 910 after expulsion of the Norse from Dublin in 902. A Hawkins (1842) illustration shows an example made from the same dies.

Three quadrants sharp and unworn, one quadrant flat.
