English Hallmarking — Assay Office Tradition
The English hallmarking tradition — the system of legally compulsory precious metal quality certification through the Assay Offices that has operated continuously in England since 1300 CE, making it the longest-running consumer protection legislation in the world. The English hallmark (comprising the maker's mark, the metal fineness mark, the Assay Office mark, and the date letter) is the closest British equivalent to the German Meisterprüfung (CRAFT-1264) and the Swiss COSC certification (CRAFT-1297), the two other quality-governance institutions the CRAFT archive documents alongside their respective national craft traditions.
