The pound sterling is subdivided into 100 pence (p), with coins available in denominations of 1p, 2p, 5p, 10p, 20p, 50p, £1, and £2. Banknotes are issued in denominations of £5, £10, £20, and £50, and are widely accepted as a means of payment throughout the country.
The value of the pound sterling fluctuates on the foreign exchange markets, and it plays a significant role in international trade and finance. It is one of the world's major reserve currencies, commonly used alongside the US dollar and euro.
Additionally, the Bank of England, the country's central bank, has the authority to issue and regulate the supply of pound sterling.
