Plate was marked at Edinburgh from 1457 onwards. Date letters started in 1681. Prior to this date, a "Deacons mark" was stamped on the piece, to be replaced by the Assay Masters mark. This practice continued until 1759 when it was replaced by a Thistle mark. The Thistle mark continued until 1975 when it was replaced by a Lion Rampant. The date letter was changed in October until the Hallmarking Act of 1975 when it (along with all other remaining British date letter sequences) changed in January.
