The British one pound (£1) coin is a denomination of the pound sterling. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction on 9 February 1983. Three different portraits of the Queen have been used, with the latest design by Ian Rank-Broadley being introduced in 1998. The current standard reverse, featuring the Royal Shield, was introduced in 2008. In addition to the standard reverse one or two new designs are minted each year.
The coin was introduced on the 9 February 1983 to replace the Bank of England one pound note which ceased to be issued at the end of 1984 and was removed from circulation on 11 March 1988, though still redeemable at the Bank's offices, like all English banknotes. One-pound notes continue to be issued in Jersey, Guernsey and the Isle of Man, and by the Royal Bank of Scotland, but the pound coin is much more widely used.
In 2017, a new 12-sided design is to be introduced. The coin is to be of a similar 12-sided shape to the pre-decimal brass threepence coin, have roughly the same size as the current £1 coin and will be bi-metallic like the current £2 coin. The new design is intended to make counterfeiting more difficult, also via an undisclosed hidden security feature.
