Extended information:

Pound banknotes are mainly issued by the Bank of England. As of 2017, the Bank of England banknotes in circulation are divided into four types: ￡5, ￡10, ￡20 and ￡50. In addition, there are many banks in Scotland and Northern Ireland that issue pounds sterling at the same time, but with different designs and denomination configurations. Internationally, only the Bank of England version is generally recognized for pound settlement.

In our country, foreign currency exchange banks do not exchange or accept pounds issued by banks other than the Bank of England. After the new version of the pound sterling issued in England is issued, the old version of the pound sterling with the same face value will generally cease to circulate soon.

However, the Bank of England accepts people to exchange old banknotes for new banknotes indefinitely. Even if the pound was issued hundreds of years ago, the Bank of England will unconditionally exchange it for the new version of banknotes after confirming that it is genuine currency.
