Regarding the moneyer, Charles Lewis Stainer writes in his Oxford Silver Pennies from AD 925-AD 1272, Vol. 46, p. xxvi (1904) "Of William Sarsorius I have not much information. He is evidently the same person as William Le Saucer, who was Mayor of Oxford about AD 1258-1259, and signs in that capacity to a deed (St. Aldate, 49) of the Hospital of St. John, now among the monuments of Magdalen College."
