British Pound

The pound sterling (symbol: £; ISO code: GBP), commonly called the pound, is the official currency of the United Kingdom, its Crown Dependencies (the Isle of Man and the Channel Islands) and the British Overseas Territories of South Georgia and the South Sandwich Islands, British Antarctic Territory and Tristan da Cunha. It is subdivided into 100 pence (singular: penny). A number of nations that do not use sterling also have currencies called the "pound".

History

The pound sterling is the world's oldest currency still in use. The full, official name, pound sterling, (plural: pounds sterling) is used mainly in formal contexts and also when it is necessary to distinguish the United Kingdom currency from other currencies with the same name.
A common slang term is quid, which is singular and plural, except in the common phrase "Quids in!" The etymology of the term is unknown, although it may derive from the Latin 'quid', possibly via the phrase quid pro quo, literally "something for something."

Coins

All the circulating coins have an effigy of Queen Elizabeth II on the obverse, and various national and regional designs, and the denomination, on the reverse. All current coins carry a Latin inscription whose full form is ELIZABETH II DEI GRATIA REGINA FIDEI DEFENSOR, meaning "Elizabeth II, by the grace of God, Queen and Defender of the Faith".
The circulating coins, excepting the two-pound coin, were redesigned in 2008, keeping the sizes and compositions unchanged, but introducing reverse designs that each depict a part of the Royal Shield of Arms and form the whole shield when they are placed together in the appropriate arrangement. The exception, the 2008 one-pound coin, depicts the entire shield of arms on the reverse.
