Pure or fine silver is too soft to be used for coinage and silverware, sculpture or jewellery. The British Silver Alloy of 92.5% silver and 7.5% copper has been in use for over 800 years and was used in Anglo Saxon pennies. The word Sterling Silver originated from the word Fosterlings.

King Henry II employed “Oosterlings” from Eastern Europe to assay coinage and silverware and it was then that 925 parts of silver in the thousand became the minimum assay standard known as Sterling Silver. The word Hallmark originated from the fact that the metallurgists or Oosterlings used town halls in which to assay and mark articles of silver.
