The quarter sovereign is a British gold bullion and collector's coin, issued by the Royal Mint since 2009. The smallest in the sovereign range, it has a face value of 25 pence.

The sovereign is a British gold coin with a nominal value of one pound sterling (£1) and contains 0.2354 troy oz 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 of the designer, Benedetto Pistrucci, are visible to the right of the date.
