This hall-mark, or town mark as it came to be known later, denotes the place where the assay was made. It was struck on all such articles as would bear the “Touch”; this is the technical term synonymous with assaying. As will be seen subsequently, the hall-mark does not stand alone. Very early it was deemed expedient to stamp some further mark, which should denote the date when the piece was actually assayed at the hall or assay office. This second assay mark, or warden’s mark, is known as the date letter. The Company of Goldsmiths in London, incorporated by charter in 1327, possessed plenary powers which they exercised with considerable rigour. They framed stringent regulations determining trade customs, they kept a watchful eye on recalcitrant members who showed any tendency to lower the dignity of the craft, and they punished with severity all those who counterfeited the official marks of the hall. This dominance over the everyday transactions of the worker in plate was supported by a series of Acts of Parliament extending over a lengthy period. They are highly technical, and the study of hall-marks is of a complex nature, and adds no inconsiderable task to the hobby of collecting old silver. In the main it will be seen that the power at first exclusively conferred on the London Goldsmiths’ Company, and afterwards distributed to various assay offices in the United Kingdom, has been kept under due subjection by the Crown and by parliamentary legislation. There is no trade more protected by Acts of Parliament governing the details of its procedure. The fashioning of gold and silver plate being so intimately related to questions of currency and affecting the coin of the realm, it is not surprising to find that the tendency of legislation has been to relieve the old guilds of much of their former power. We find that one of the recommendations of the Select Committee of the House of Commons on hall-marking, in 1879, was that the whole of the assay offices should be placed under the supervision of the Royal Mint, in order that a uniform standard of quality should be guaranteed. We have seen that the London assay office is the _doyen_ of assay offices. At first, plate, although wrought elsewhere, had to bear the London hall-mark of the leopard’s head. Seven cities were appointed, by a statute of Henry VI in 1423, to exercise the right of assaying plate, viz. Salisbury and Bristol for the West Country, Newcastle and York for the North Country, Coventry for the Midlands, Lincoln and Norwich for East Anglia, and London, of course, continued its functions.
