Standard Gold

Originally, standard gold meant metal that was 916 fine; this was the commonly traded purity until the twentieth century. Thus the sterling price of gold set at £3.17.10½ d in 1717 was per standard troy ounce; the price for fine gold (then not refined) was the equivalent of £4.4.11½ d.

The term ‘standard gold’ was used in all London gold market and Bank of England documents until the beginning of the twentieth century when the phrase good delivery for 995 gold replaced it.

The term ‘standard gold’ is still used in India to describe the 916 fine (22 carat) bars normally traded in the Bombay market.

In the United States it refers to an alloy 900 fine, with the balance in copper, used for coinage.
