The Bank of England, which is now the Central Bank of the United Kingdom, has issued banknotes since 1694. In 1921 The Bank of England gained a legal monopoly on the issue of banknotes in England and Wales, a process that started with the Bank Charter Act of 1844 when the ability of other banks to issue notes was restricted.
Banknotes were originally hand-written; although they were partially printed from 1725 onwards, cashiers still had to sign each note and make them payable to someone. Notes were fully printed from 1855. Since 1970, the Bank of England's notes have featured portraits of British historical figures.
Of the eight banks authorised to issue banknotes in the UK, only the Bank of England can issue banknotes in England and Wales, where its notes are legal tender. Bank of England notes are not legal tender in Scotland and Northern Ireland, but are accepted there along with other notes.
All current Bank of England banknotes are printed by contract with De La Rue at Debden, Essex. They include the printed signature of the Chief Cashier of the Bank of England. All the notes issued since Series C in 1960 also depict Elizabeth II of the United Kingdom in full view facing left and as a watermark, hidden, facing right; more recent issues also include the EURion constellation. The custom of depicting historical figures on the reverse began in 1970 with Series D, designed by the bank's first permanent artist, Harry Eccleston. The Bank of England Series D £1 note was discontinued in 1984, having been replaced by a pound coin the year before.
