when did the one pound coin come into circulation
21 April 1983
title: One pound (British coin) text: One pound (British coin) The British one pound (£1) coin is a denomination of the pound sterling. Its obverse bears the Latin engraving ELIZABETH II D G REG “Dei Gratia Regina” meaning, “Elizabeth II, by the grace of God, Queen” and F D 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 title: One pound (British coin) text: 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. 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 title: One pound (British coin) text: 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on 28 March 2017 and both new and old versions of the one pound coin circulated together until the older design was withdrawn from circulation on 15 October 2017.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 round pound remains legal tender on the Isle of Man. The main purpose of redesigning the coin was to combat counterfeiting. As of March 2014 title: One pound (British coin) text: the original coin was changed each year from 1983 to 2008 to show, in turn, an emblem representing the UK, Scotland, Wales, Northern Ireland, and England, together with an appropriate edge inscription. This edge inscription could frequently be "upside-down" (when obverse is facing upward). From 2008, national-based designs were still minted, but alongside the new standard version and no longer in strict rotation. The inscription appeared on all reverse designs. In common with non-commemorative £2 coins, the round £1 coin (except 2004–07 and the 2010–11 "capital cities" designs) had a mint mark: a small crosslet found on the milled edge title: One pound (British coin) text: that represents Llantrisant in South Wales, where the Royal Mint has been based since 1968. The reverse of the new 12-sided, bimetallic pound coin, introduced on 28 March 2017, was chosen by a public design competition. The competition to design the reverse of this coin was opened in September 2014. It was won in March 2015 by 15-year-old David Pearce from Walsall, and unveiled by Chancellor George Osborne during his Budget announcement. The design features a rose, leek, thistle and shamrock bound by a crown. All years except 1998 and 1999 have been issued into circulation, although the number issued
