British Silver and Gold Hallmarking from 1300 AD to present

 

Hallmarking is necessary because when jewellery is manufactured, precious metals are not used in their pure form, as they are unworkable. Gold, Silver, and Platinum are always alloyed with copper or other metals to create an alloy that is more suitable to the requirements of the jeweller. Such an alloy needs to be strong, workable and attractive.

Due to the high value of gold, platinum and silver, there are significant profits to be gained by reducing the precious metal content of an alloy at the manufacturing stage. Even an expert cannot determine the quality or standard of precious metal items by eye or touch alone. Base metal articles plated with a thin coat of gold or silver are indistinguishable from the same articles made wholly of precious metal until subjected to expert testing.

With volume manufacturing, enormous profits can be made from undercarating. Without compulsory independent testing there is huge potential for deception and fraud.

The UK Hallmarking system has offered valuable protection for over 700 years. Compulsory Hallmarking protects all parties; the public who receive a guarantee of quality, the manufacturer who is given quality control and protection from dishonest competitors at a very low cost and the retailer who avoids the near impossible task of checking standards on all his goods.

The date letter system was introduced in London in 1478 (elsewhere as the hallmarking system evolved). Its purpose was to establish when a piece was presented for assay or testing of the silver content. The mark letter changed annually in May, the cycles of date letters were usually in strings of 20 and each cycle was differentiated by a changing of the font, letter case and shield shape.

In 1784 the duty mark was created to show that a tax on the item had been paid to the crown. The mark used was a profile portrait of the current reigning monarch’s head. The use of this mark was abolished in 1890.

The enforced use of the maker’s mark was instituted in London in 1363. Its purpose was to prevent the forgery of leopard’s head marks upon silver of debased content. Originally, makers’ marks were pictograms, but by the beginning of the 17th Century it had become common practice to use the maker’s initials.

The Chinese call England “The Island of Hero’s” which I think sums up what we English are all about.
