The currency of the UK is the Pound Sterling (or more normally, just Pound). The Bank of England produces all of the banknotes for England and Wales, whilst several banks in Northern Ireland and Scotland produce notes to their own designs. Jersey, Guernsey and the Isle of Man also issue their own notes. The only notes in current issue in England are £5, £10, £20 and £50. Scotland, Jersey, Guernsey and the Isle of Man also have £1 notes. Scotland and Northern Ireland also issue £100 notes.
Paper notes were printed in denominations between £20 and £1000 from as early as 1855.
