Very rare, and possibly unique surviving example of a 6⅞” diameter flat plain rim paten or flagon plate c1603-25. Made by an unidentified pewterer and struck to the reverse of the rim with a crowned rose touch flanked by 'I R'. This mark may refer either to the maker (PS8170) or to it being an export piece from the reign of King James I (see article 'The Crowned Rose as a secondary touch' by the late Jan Gadd in JPS Autumn 1999 pp42-55) Described by Chris Peal in More Pewter Marks (MPM 5888a) as a 'flagon plate' this extremely shallow plate may have served that purpose, or as a paten. In superb condition for its age, with light-medium grey original surface patina to obverse and darker grey reverse. Illustrated and described at Fig 308 p125 Pewter of the Western World. Provenance: formerly in the collections of the late AV Sutherland Graeme (his #16 sold as Lot 78 Sotheby's 6.10.1981), and Barbara Muller CT. 202g weight.
