Hallmarks are marks applied to precious metals to indicate the amount of pure metal in the alloy. Traditionally applied by striking with a punch, hallmarks can now also be applied using lasers.

The oldest Assay Offices are working from Royal Charters (London and Edinburgh). The Goldsmiths’ Company Assay Office began hallmarking in 1327.

If a pieces of silver is below 7.8gm it is exempt from hallmarking.
