Introduced as a round coin in 1983. The UK pound coin originally replaced the Bank of England £1 note.
The current 12-sided UK pound coin was first circulated on the 28th March 2017. The older UK pound coin was demonetised on the 14th October 2017. Banks still accept the older £1 coins.
See this page for the 1983 – 2016 round £1 coins.
