British gold coin, introduced by Henry VII, which became the standard monetary unit in 1817. Minting ceased for currency purposes in the UK in 1914, but the sovereign continued to be used as “unofficial” currency in the Middle East. It was minted for the last time in 1987 and has now been replaced by the Britannia.
The value is notionally 1, but the actual value is that of the weight of the gold at current rates.
