Bank of England note issues
The Bank of England, 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 1844, when the power of other banks to issue notes was restricted.
