At present 200 procuratorial stamped tiles are known from Roman Britain, the vast majority from the City of London. A small number of other stamps are known from Westminster, Barking in Essex, Brockley Hill in Hertfordshire, and possibly Saunderton in Buckinghamshire. Eight procuratorial stamped mortaria have also been found in London. All the procuratorial stamped tiles found up to 1986, with two exceptions found too late for inclusion, are listed in RIB II. The considerable number of stamped tiles found in London after this date, almost all of them unpublished, are included in an appendix to this report.
