Wales uses the same currency as the rest of the United Kingdom, the British Pound Sterling.
The currency is the same (Pounds Sterling) but the issuing banks, and therefore the design of the notes, are different. In England and Wales all notes are issued by the Bank of England. In Scotland, notes are issued by a few different banks, so there's all sorts of designs floating about.ome Scottish banks issue their own banknotes but they are accepted in Scotland and in some places in England & Wales. Northern Ireland banks also issue their own banknotes but they are rarely accepted outside Northern Ireland.
