What is a Hallmark?

Until 1998, a Hallmark consisted of four COMPULSORY MARKS.  Since 1998 the date letter has become optional but the other three symbols remain compulsory. The symbols give the following information:

  • who made the article
  • what is its guaranteed standard of fineness
  • the Assay Office at which the article was tested and marked
  • the year in which the article was tested and marked
