Cloth Seal, William III, Alnage, Image & Found by Alex Hilton.
Found in Yorkshire, 12mm.
Missing // head facing right, OF ENG LAND around // three fleur-de-lis in inverted triangle 1 (1/2) to sides of the lower fleur-de-lis
See No.137 Fig.27, Egan, 1994, Lead cloth seals and related items in the British Museum, British Museum Occasional paper 93. Portrait of James II compares reasonably well but the nose is not a good match, also see No.142 Fig.27 which has a disc matching the fleur-de-lis design and that seal is tentatively attributed to William III.
ALNAGE SEALS AND THE NATIONAL COINAGE - SOME PARALLELS IN DESIGN, G EGAN - Brit. Numis. J. 61, 31, 1991. Has the following to say:-
"A few seals with the heads of William and Mary together are known, but there is no very close comparison with other representations on coins or elsewhere. After Mary's death, the head used for William, clearly identifiable on a large number of alnage seals from his hooked nose (pi. 5, 12C), continues the style used for the heads of Charles and James, with a depiction just about as close to the representations of these earlier monarchs as it was possible to get. There are two engraved lines at the nose on the head in pi. 5, 12D (very faint), and it is tempting to think that the administrators of the alnage, which around this time was coming under increasing criticism for its ineffectiveness as a means of quality control, sought to save money by having a matrix for Charles or James slightly altered, rather than commissioning the cutting of an entirely new one. There is no hint of alteration on the great majority of seals attributable because of the hooked nose to William, so some new matrices must have been cut during his reign. The continued use of what was, in origin, an early-Restoration portrait of Charles II, through many developments in style on coins, is symptomatic of the inertia in an organisation that had outlived its usefulness to all but the tiny number of beneficiaries from the subsidy, who treated the entire business as a source of personal revenue."
The portrait on this seal is a better match to that shown in 12D in the above paper and therefore will be assigned to William III.
