The sovereign is a British gold coin with a nominal value of one pound sterling (£1) and contains 0.2354 troy ounces (113.0 gr; 7.32 g) of pure gold. Struck since 1817, it was originally a circulating coin that was accepted in Britain and elsewhere in the world; it is now a bullion coin and is sometimes mounted in jewellery. In addition, circulation strikes and proof examples are often collected for their numismatic value. In most recent years, it has borne the design of Saint George and the Dragon on the reverse; the initials (B P) of the designer, Benedetto Pistrucci, are visible to the right of the date.
The coin was named after the English gold sovereign, which was last minted about 1603, and originated as part of the Great Recoinage of 1816.
