The Saint Helena pound is the currency of the Atlantic islands of Saint Helena and Ascension, which are constituent parts of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha. It is fixed at parity with the pound sterling and as such both currencies are commonly accepted and circulated. It is subdivided into 100 pence. Tristan da Cunha, the third part of the territory, officially adopted the Pound sterling. However, there are occasionally commemorative coins minted for the island.
