Alan found out: "Lockett collection included an example reading BRVNHYSE ON COLE (lot 813 part), which is how I would read your coin.

King Edward the Confessor (c. 1003 – 5 January 1066), son of Ethelred the Unready, was the penultimate Anglo-Saxon King of England and the last of the House of Wessex, ruling from 1042 until his death. His reign marked the continuing disintegration of royal power in England and the aggrandizement of the great territorial earls, and it foreshadowed the country's later connection with Normandy, whose duke William I of England was to supplant Edward's successors Harold Godwinson and Edgar Ætheling as England's ruler.
Edward succeeded his half-brother Harthacanute, who had successfully regained the throne of England after being dispossessed by his half-brother, Harold Harefoot. Edward and his brother Alfred the Ætheling, both sons of Emma of Normandy by Ethelred the Unready, had previously failed to depose Harold in 1036. When Edward died in 1066 he had no son to take over the throne so a conflict arose as three men claimed the throne of England.
