The 2017 One Pound Coin. The new 12-sided, bi-metallic one-pound coin was first minted in 2016 although the coin itself did not become legal tender until March 2017.
The early production was to allow the mint enough time to produce enough coins to replace the 1.6 billion old round one-pound coin which would cease to be legal tender by on 15 October 2017. After that date the coin is effectively worthless (unlike UK banknotes which can always be redeemed by the Bank of England). The Royal Mint issued 640 million one-pound coins in 2017.
The new 12-sided bi-metallic design is intended to make counterfeiting more difficult, via an undisclosed hidden security feature, called 'iSIS' (Integrated Secure Identification Systems). The round pound suffered from forgeries with an estimated 1-in-30 as fake.
The basic specification is:
The Reverse shows a Rose, leek, thistle, and shamrock encircled by a coronet which are the Nations of the Crown representing the United Kingdom. Designer is David Pearce.
The Obverse is a portrait of Queen Elizabeth II by Jody Clark.
