plate mark

In Scotland the marks on silver of 11 oz. 2 dwts. are precisely the same as those on gold of 22 carats standard; and so it was, also, in England until the 7 & 8 Vict. c. 22, by s. 15 of which the gold plate mark was altered.

All four beveled edges of the plate should correspond with the embossed plate mark on the back of the print.
