Pound sterling in the South Atlantic and the Antarctic

The United Kingdom possesses a number of islands in the South Atlantic Ocean as well as a section of the Antarctic continent. These territories are St. Helena with Ascension Island and Tristan da Cunha, the Falkland Islands, South Georgia and the South Sandwich Islands, and the British Antarctic Territory. The official currency in these territories is either Pound sterling or a local currency that evolved from sterling and is at a fixed one-to-one parity with sterling.

Until 1929–1930, when the Australian pound and New Zealand pound ceased to be at parity with sterling, sterling was the currency of much of the Antarctic continent, including the Australian Antarctic Territory and the Ross Dependency.

St. Helena used sterling currency as in the United Kingdom until 1976 when it began to issue its own banknotes at par with the pound sterling. In 1984, this territory also began to issue its own coinage, similar to the coinage of the United Kingdom but with different designs on the reverse. The St. Helena currency also circulates on Ascension Island, but not in the other part of the territory, Tristan da Cunha, where UK currency circulates.

The Falkland Islands used sterling currency as in the United Kingdom until 1899 when it began to issue its own banknotes at par with the pound sterling. In 1974, this territory also began to issue its own coinage, similar to the coinage of the United Kingdom but with different designs on the reverse.
