Britain always used the standard 925 and had another standard which is 950 silver which was called Britannia silver (this Britannia silver is seldom seen) and instead of the Lion rampant or lion Pageant you would see Britaina.Britain never used a standard less than 925.Hence why British silver is sought after pre-1900 hundreds. Britain would not accept any standard below 925 as silver. Most European countries up until 1920s used 830s. Scandinavian countries used 830s silver like Denmark moved to using 925 silver in 1927 however even though a higher grade of silver was used by most jewellers in Scandinavia, they stuck to stamping there jewellery 830s as they did not have to pay a tariff to the assaying office for the change over to 925. So most Jewellery made by fine houses in Scandinavia will in fact be marked 830s but will have a standard silver of 925. Places like Egypt still today only use 830 silver
