Banknotes have been issued for use specifically in Northern Ireland since 1929, and are denominated in pounds sterling. They are legal currency in Northern Ireland but technically not legal tender in any other country in the United Kingdom (or other territories which use sterling)[1]. However, the banknotes are still widely accepted as currency by larger merchants and institutions elsewhere in the United Kingdom. Issuing banks have been granted legal rights to issue currency, and back the notes with deposits at the Bank of England.
