Medieval English Silver Coin of King William the Conqueror (Conqueror of England)

Silver penny of William I of England, struck in the closing years of his reign and bearing the distinctive “PAXS” reverse type. Issued between 1083 and 1086, this coin belongs to the final series produced during William’s lifetime, just before his death in 1087.

The obverse features a crowned bust of William holding a scepter, with the legend “+ PILLELM REX,” a Latinized rendering of “King William.” The reverse displays a cross potent design with the inscription “P A X S” — Latin for “peace.” The inclusion of this legend has long been interpreted as a proclamation of stability after the turbulent decades following the Norman Conquest of 1066. The reverse also names the moneyer, Sæwine, and identifies the Wilton mint — a provincial but historically significant production center.

Struck in fine silver and weighing approximately 1.5 grams, the penny was the backbone of Norman England’s monetary system. William maintained tight royal control over coinage, ensuring uniform design and authority across the kingdom. This issue was minted around the time of the Domesday Book’s completion, a landmark administrative achievement.

A scarce Wilton example, this “PAXS” penny represents William’s final monetary statement — a silver testament to conquest, consolidation, and royal authority in medieval England.
