<Tr> <Th> Design date </Th> <Td> 2016 </Td> </Tr> <P> The British one pound (£ 1) coin is a denomination of the pound sterling . Its obverse bears the Latin engraving ELIZABETH II DG REG "Dei Gratia Regina" meaning, "Elizabeth II, by the grace of God, Queen" and FD meaning Fidei defensor, Defender of the Faith . It has featured the profile of Queen Elizabeth II since the original coin's introduction on 21 April 1983 . Four different portraits of the Queen have been used, with the latest design by Jody Clark being introduced in 2015 . The design on the reverse side of the current, 12 - sided coin features four emblems to represent each of the nations of the United Kingdom--the English rose, the leek for Wales, the Scottish thistle, and the shamrock for Northern Ireland--emerging from a single stem within a crown . </P> <P> The original, round £ 1 coin replaced the Bank of England £ 1 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 . A new, dodecagonal (12 - sided) design of coin was introduced on 28 March 2017 and both new and old versions of the one pound coin circulated together until the older design was withdrawn from circulation on 15 October 2017 . After that date, the older coin could only be redeemed at banks, although some retailers announced they would continue to accept it for a limited time . The original round pound remains legal tender on the Isle of Man . </P> <P> The main purpose of redesigning the coin was to combat counterfeiting . As of March 2014 there were an estimated 1,553 million of the original nickel - brass coins in circulation, of which the Royal Mint estimated in 2014 that just over 3% were counterfeit . The new coin, in contrast, is bimetallic like the current £ 2 coin, and features an undisclosed hidden security feature called "iSIS" (Integrated Secure Identification Systems). </P>
