S.1318, Eustace FitzJohn -

‘Ornamented’ series, helmeted knight standing right, holding upright sword, EVSTA[CIVS], rev. cross within quatrefoil, surrounded by random letters (some retrograde) interspersed with symbols.  Refs: (Allen, NC 2016, 123, perhaps same dies; cf. Mack 224; N 929c; S 1318).   Martin Allen of the Fitzwilliam notes that this reverse die is the same as some examples from William of Aumale, thus forming the first recorded die link between the coins of William of Aumale and Eustace Fitz John.   Robert Page collection, DNW 05-06-19 #616.  A 2019  detecting find by Kev Gorman.
