Britannia coins are British bullion coins issued by the Royal Mint in gold since 1987 and in silver since 1997. The original Britannia silver coins contain one troy ounce (1 oz) of silver and have a face value of £2.
Silver Britannias are also issued in fractional sizes of one-half, one-quarter, one-tenth, 1/20th and 1/40th of a troy ounce and with face values of £1, 50p, 20p, 10p and 5p respectively. There is also a five-ounce coin of face value £10.
Britannia as a symbol has been depicted on British coinage for centuries. The bullion series called Britannia has been issued in gold since 1987 and in silver since 1997; it has a "definitive" depiction - used on bullion coins (Brilliant Uncirculated grade), as well as “Britannia, the Changing Face of Britain” - a series of one-year designs like this one - used on proofs made for collectors.
While firmly rooted in the times of the Romans, a modern Britannia has emerged, appearing as a symbol of design excellence in high fashion magazines and associated with all things fashionable during the ‘Cool Britannia’ phase in the 1990s. On the 20th anniversary of the silver Britannia bullion coin, fine art student Louis Tamlyn has created a contemporary reverse design, reflecting a time of political change when the eyes of the world have often been on Britain. His design also contains a trident mint mark that celebrates these important anniversaries.
