Sovereign (British coin) Named after the English gold sovereign, last minted in 1604, the name was revived with the Great Recoinage of 1816.[2] Minting these new sovereigns began in 1817. By the coin act of 1816, 12 Troy ounces of 22-carat gold were worth 44.5 Guineas (a Guinea being £1.05). This meant that the 1-pound sovereign should weigh 160/623 ounces (~0.257 oz or 7.98 g), whereas its content of pure gold was 22/24 of this (~0.23542 oz or ca. 7.322381 g). This weight has remained almost constant — rounding at 10−6 g took place on its legal redefinition in the decimalised rather than fractional system of coin weights.[3]
