Gold standard

During the American War of Independence and the Napoleonic wars, Bank of England notes were legal tender, and their value floated relative to gold. The Bank also issued silver tokens to alleviate the shortage of silver coins. In 1816, the gold standard was adopted officially, with silver coins minted at a rate of 66 shillings to a troy pound (weight) of sterling silver, thus rendering them as "token" issues (i.e. not containing their value in precious metal). In 1817, the sovereign was introduced, valued at 20/–. Struck in 22‑carat gold, it contained 113 grains or 7.32238 g (0.235420 ozt) of fine gold and replaced the guinea as the standard British gold coin without changing the gold standard.
