Sterling is the currency in Gibraltar. Bank of England issued notes and UK coins are accepted, and circulate mixed with locally issued notes and coins of the same value in pounds and pence. Notes issued in Scotland or Northern Ireland are not usually accepted in Gibraltar, and Gibraltar issued notes and coins are not usually accepted in the UK.
Some businesses accept euros, although exchange rates may not necessarily be favourable. Change is normally given in Sterling. UK debit cards and all major credit cards are widely accepted in Gibraltar.
