- Hallmarks - A mark stamped on articles of precious metals in Britain, since the 14th century, certifying their purity. It derives its name from the Guild Hall of the Goldsmiths' Company, who recieved its Charter in 1327 giving it the power to assay (test the purity) and mark articles of gold and silver.
The hallmark will consist of several marks, including the:
- silver standard mark, indicating the purity of the metal. Sterling silver is .925 pure silver.
- the city mark indicating the city in which it was assayed eg London, Birmingham, York etc.
- the date mark, usually a letter of the alphabet in a particular font and case,
- a duty mark, indicating whether duty had been paid to the crown, and only in use from 1784 to 1890
The piece may include an additional mark, the maker's mark, although not forming part of the hallmark, will be located in the vicinity of the hallmarks.
Sometimes silver plated items will bear faux hallmarks, often confusing those not familiar with silver markings.
- Tankard - A tankard is a drinking vessel for beer, ale, and cider, similar in shape to a large mug, and usually with a hinged lid. Silver tankards were in use in Britain and other parts of Europe from at least the sixteenth century, pewter tankards probably from the thirteenth. In the 19th century a number of ornately carved ivory tankards were produced, but these were designed to demonstrate the skill of the carver, rather than for day to day use. The shapes of tankards vary, sometimes globular, sometimes a tapering concave. For those with lids, the lid usually includes a thumbpiece that the drinker can hold down to keep the lid open. Variation in the design of the thumbpiece include wedge, ball and wedge, ball, hammer head, bud and wedge, double volute (scroll), chair-back, ball and bar, shell, double acorn, corkscrew, and ram's horn.
- Britannia Standard - A higher grade of silver than sterling silver. Britannia standard silver contains at least 958 parts per thousand of pure silver, while sterling silver contains at least 925 parts per thousand of pure silver.
The Britannia standard was obligatory in Britain between 1697 and 1720 and after that was optional, so there are very few silver items that come onto the market that are Britannia standard.
Not to be confused with silver plated Britannia metal items, often marked as "EPBM", a pewter type alloy, that when unplated can be temporarily polished to a silver-like lustre.
