Britannia silver has a millesimal fineness of at least 958. The alloy is 95.84% pure silver and 4.16 per cent copper or other metals.
The Britannia standard was developed in Britain in 1697 to help prevent British sterling silver coins from being melted to make silver plate. It was obligatory in Britain between 1697 and 1720, when the sterling silver standard was restored. It became an optional standard thereafter.
