Answer 2

Answer:

The purity of gold and silver bars/coins is normally referred to as “the millesimal fineness”. This measures the overall purity of precious metals based on parts per thousand. For example, if a gold bar has a fineness of 999 then it is made up of 999 parts gold to 1-part other metals.
