Symbol guide
Birmingham silver hallmarks date letters are recognised by its assay-office device: anchor. The anchor is the office mark.
The anchor is the office mark. Its orientation can vary with the article and period, so do not use orientation alone to assign a date. From 1975 London, Birmingham, Sheffield and Edinburgh use the same sequence; 2025 restarts at A. The letter J is omitted from that modern 25-letter cycle.
Compare the letter’s case, exact typeface and shield, not just its alphabetic name. A date letter records the assay year. Use the sponsor’s working dates and the other punches to distinguish repeated letters in older cycles.
