LONDON [Illustration: 1779] [Illustration: 1798] [Illustration: 1826] EXETER [Illustration: 1748] The date letters of the various London alphabets are readily ascertainable. The differences in the shape of the shields are not great; the leopard lost his crown in 1821 and has been cat-like in appearance ever since. Exeter continued as an Assay Office till 1882, but York, which was not mentioned among the Assay Offices in 1773, recommenced about the beginning of the nineteenth century and continued till 1870. Its mark was a St. George's Cross and five diminutive Lions. Newcastle-upon-Tyne similarly discontinued assaying silver in 1884. =Exeter.=--The mark, as is shown, is a castle with three towers. The Date Letters were =A-Y= (1773-1796). The letter =I= was used for two years 1781 and 1782. =A-U= (1797-1816) in square shield and =a-u= (1817-1836) in square shield with four corners cut off. About 1775 the following silversmiths' marks are found on Exeter silver: Richard Jenkins, William Coffin, Richard Freeman, and Thomas Thorne (Plymouth), David Hawkins (Plymouth), William Harvey (Plymouth), Richard Bidlake (Plymouth). =Chester.=--The Town Mark formerly was three Demi-Lions with wheatsheaves on a shield. In 1775 it was changed to three Wheatsheaves with a dagger, which is still in use at the Chester Assay Office. In addition there is the Lion passant and the Leopard's head denoting sterling silver, as at London. =Newcastle-upon-Tyne.=--The complete Marks are the Lion passant, the Leopard's head, the Town or Hall mark of three Castles, the Date Letter, the Maker's Mark, and the Duty Mark of the sovereign's head used, as at all other offices, till 1890, when the duty on silver plate was abolished.
