Struck during the joint reign of William and Mary, the 1691 William & Mary Maundy Set reflects a significant moment in British royal history. Issued for the Royal Maundy ceremony, these small silver coins were specially prepared for presentation by the monarchs as part of a long-standing tradition of charity and service.

The set includes the one penny, two pence, three pence and four pence pieces, each struck in sterling silver. 

The obverse carries the joint portrait of William and Mary, a distinctive design that marks the shared monarchy of the period. The reverses display crowned numerals, a design that would become synonymous with Maundy coinage and endure in British numismatics for generations. Together, these details give the pieces strong historical appeal and clear collector interest.

By this time, Maundy coins were being struck as milled pieces, giving them a more regular shape and a cleaner finish than earlier hand-made coinage. This is an important detail for numismatists, as it reflects the growing precision of the Royal Mint in the late 17th century. Complete sets from the reign of William and Mary are especially desirable, particularly when all four denominations remain well matched.

With its royal connection, refined silver finish and place in the continuing story of Maundy money, the 1691 William & Mary Maundy Set offers collectors a handsome and historically important link to the age of William and Mary.
