History
Edinburgh's Assay Office is the older of the two historically active Scottish offices (the other, Glasgow, closed in 1964). The three-towered castle town mark predates London's continuous date-letter system; record-keeping is patchy before 1681 but the mark itself is documented from 1457. The Incorporation of Goldsmiths of the City of Edinburgh remains the governing body.
Reading the marks on a Edinburgh piece
Scottish silver does not use the Lion Passant. Historically Edinburgh's standard mark was the Thistle (1759–1974), then the Lion Rampant from 1975 onwards, alongside the three-towered castle town mark. Pre-1759 pieces use a deacon's mark — this is a cycle-specific mark that varies by year and requires expert reference for accurate dating. From 1975 the Lion Rampant signals sterling silver assayed in Scotland.
Identifying the date — using the date letter
Edinburgh ran an independent date-letter cycle until 1975, when it joined the unified UK sequence. Pre-1759 dating relies on the deacon's mark rather than a date letter. The Edinburgh Assay Office publishes its chart on its hallmarking pages.
