The pound sterling (symbol: £; ISO code: GBP), known in some contexts simply as the pound or sterling, is the official currency of the United Kingdom, Jersey, Guernsey, the Isle of Man, Gibraltar, South Georgia and the South Sandwich Islands, the British Antarctic Territory, and Tristan da Cunha. It is subdivided into 100 "pence" (singular: "penny", abbreviated: "p"). The “pound sterling” is the oldest currency in continuous use. Some nations that do not use sterling also have currencies called the "pound".
