when did the new £1 coins come into circulation
One pound (British coin) Since 28 March 2017, two versions of the one pound coin have been in circulation – the original round design and a new dodecagonal (12-sided) design.[3] As of March 2014 there were an estimated 1,553 million round £1 coins in circulation,[4] of which the Royal Mint estimated in 2014 that 3.04% (i.e. about 47 million) were counterfeit.[5][6] In an effort to counter this, the Royal Mint introduced the new 12-sided coin, which is bimetallic like the current £2 coin, and features an undisclosed hidden security feature called 'iSIS' (Integrated Secure Identification Systems).[7][8] The round pound will remain in circulation until 15 October 2017. After that date, the older coin can only be redeemed at banks.[9]

Florin (British coin) Florins (usually dated 1947 or later) remained in circulation after Decimal Day. In 1987, following a study of the currency, the Thatcher government announced its intent to issue a new ten pence piece, reduced in size.[39] A smaller ten pence piece was issued in 1992, after which the old florin was demonetised on 30 June 1993. The florin, the first decimal coin, was the last coin in general circulation just prior to decimalisation to be withdrawn.[40]
