Penny - William I Paxs type

The Paxs type takes its name from the word struck across the reverse — an unusual choice that some historians link to William's efforts to project ecclesiastical authority and domestic order during a period of baronial unrest in the early 1080s. It was the final type of his reign, superseded only by his death in 1087 following injuries sustained at the Siege of Mantes.

Dies were cut and distributed to licensed moneyers operating across roughly sixty English mints, a system inherited from the late Anglo-Saxon administration that William pragmatically kept intact.
