A digital app revised from the best-selling ‘Jackson’s Silver & Gold Marks of England, Scotland and Ireland is now available to download.

Hallmarks, from The Antique Collectors' Club, priced at £4.99, contains complete cycles of silver marks for all the important Assay offices, with variations shown for gold, platinum, Britannia standard and import marks.

For the smaller centres, selections of marks have been chosen to give the most important variations likely to be found, while a selection of makers' marks include not only the important or interesting names, but also the most prolific manufacturers and retailers.

Comments after a particular maker indicate the type of work produced (e.g. spoon maker), possible confusion with other makers, and points to look for (e.g. a connection with an important designer).
