British Coins

British coins are produced by the Royal Mint. The same coinage is used across the United Kingdom: unlike banknotes, local issues of coins are not produced for different parts of the UK. The pound coin until 2016 was produced in regional designs, but these circulate equally in all parts of the UK. 

An extensive coinage redesign was commissioned by the Royal Mint in 2005, and new designs were gradually introduced into the circulating British coinage from summer 2008. Except for the £1 coin, the pre-2008 coins remain legal tender and are expected to stay in circulation for the foreseeable future. The 1p and 2p coins from 1971 are the oldest standard-issue coins still in circulation. 

Since decimalisation on 15 February 1971 the pound has been divided into 100 pence. (Prior to decimalisation the pound was divided into 20 shillings, each of 12 [old] pence; thus, there were 240 [old] pence to the pound.) The pound remained as Britain's currency unit after decimalisation.
