The Bank of England £100,000,000 note, also referred to as Titan, is a non-circulating Bank of England sterling banknote used to back the value of Scottish and Northern Irish banknotes. It is the highest denomination of banknote printed by the Bank of England. As both Scotland and Northern Ireland have banknotes issued by particular local banks, the non-circulating notes provide the essential link between those banknotes and the currency of England and Wales, and security if a local issuing bank were to fail.
