The sovereign is a gold coin of the United Kingdom, with a nominal value of one pound sterling. Struck from 1817 until the present time, it was originally a circulating coin (see pre-decimal Sovereign) accepted in Britain and elsewhere in the world; it is now a bullion coin not intended for circulation, the intrinsic value of which is much higher than its face value. There are several denominations of the Sovereign: Five Sovereigns (Quintuple Sovereign, five pounds gold), Double Sovereign, Full Sovereign, Half Sovereign and Quarter Sovereign; the current sovereign - with face value of £1 is a continuation of the pre-decimal sovereign, and has been issued as a decimal coin since 1974.
Apart from the sovereigns of the United Kingdom, the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha has also authorised some mints to issue sovereigns under its jurisdiction. These are denominated in Saint Helena Pounds - the local variation of the Pound Sterling. Following long-standing tradition, this type of coin has never had its value and denomination spelled out anywhere on the coin.
