At the beginning of the eighteenth century three out of these seven, Lincoln, Salisbury, and Coventry, had discontinued to assay silver, and it was not thought necessary to reappoint them. In 1700 York, Bristol, and Norwich were, in the reign of William III, reappointed for assaying and marking wrought silver. By the same Act, 12 William, _cap._ 4, two new assay offices were appointed, Exeter and Chester, and in the beginning of the following reign by 1 Anne, _cap._ 9, Newcastle was also reappointed. At the end of the eighteenth century, in 1773, two additional assay offices were created at Birmingham and at Sheffield by 13 George III, _cap._ 52. London, during all this time had continued to assay silver in unbroken continuity from the fourteenth century. It has been estimated by those who have a large quantity of old silver plate passing through their hands, that, in spite of the number of provincial assay offices, over 90 per cent. of old English silver bears the London hall-mark. The Hall-marks of the Various Assay Offices In the Appendix (pp. 347-409) are illustrations showing the various hall-marks used at different periods by the wardens and assay masters of the appointed cities. The following indicate the chief marks used. =London= (the leopard’s head, sometimes like a king on a pack of cards, and later, when uncrowned, like a tiger’s head). =Chester= (an upright sword between three wheatsheaves). =Newcastle=, closed in 1884 (three castles set in a shield, two over one, similar in arrangement to the Chester wheatsheaves). =Exeter=, closed in 1883 (early mark letter X with crown above. After 1701 three castles, sometimes joined together as one castle with three towers, similar to Edinburgh mark). =Norwich= (castle above with lion beneath; the castle is less like a castle than any other of the castle marks). =York=, closed in 1856 (early mark a fleur-de-lis, showing only half, the other half undecipherable, conjectured by some authorities to be a rose, by others a leopard’s head; this latter is now accepted as correct, and clearly shows in some examples; later mark shield with cross of England and five lions). =Birmingham= (an anchor), =Sheffield= (a crown), =Edinburgh= (a castle with three towers). =Glasgow= (a tree with a bird perched on top, and a tiny bell suspended from boughs, a fish transversely across the trunk). =Dublin= (figure of Hibernia since 1730). Cork (ship and castle, two marks). The Varying Number of Marks Used
