It is an interesting fact, and extremely puzzling to beginners in the study of hall-marks, to find that the provincial offices used, in addition to their own place-mark, the leopard’s head of the London assay office. From 1697 to 1719 the leopard’s head disappears from all silver, for the reason which is given in detail in Section V of this chapter--“The Higher Standard Mark” (pp. 49-59). In its place two other marks occur--the lion’s head erased and the figure of Britannia. These were only used in London between the years 1697 and 1701, during which five years provincial offices ceased to assay any silver. This is a hiatus in provincial marks which the beginner should note. From 1701 to 1719 the provincial offices used their place-marks together with the two new marks (the lion’s head erased and the figure of Britannia), which were compulsory by law. This law was repealed in 1719 and London reverted to the old style mark of the leopard’s head, so that London-marked silver of 1720 is marked with the same number of marks as that before the Act of 1697, that is four marks. But it appears that the provinces for a long period did not revert to the old style of marking. Newcastle, for instance, adds the leopard’s head from 1720 in addition to her town mark; Exeter similarly took the leopard’s head in 1720. Chester also added another mark, the leopard’s head, at the same time. The result of this is that before 1701 Chester had four marks, sometimes only three, but after 1720 five were used; when the duty mark was added (see p. 395) six marks were employed. The leopard’s head was not discontinued till 1839, reducing the marks to five, and now, since the abolition of the duty mark in 1890, there are only four. Exeter had, with the use of the leopard’s head, five marks, but in 1748 the leopard’s head had disappeared. Newcastle continued the leopard’s head during the period of the duty mark, thus making six marks, till the closing of the office in 1884. II. THE STANDARD MARK
