New pound coin designed to combat counterfeiting

20 March 2014 Last updated at 00:34 GMT

A new £1 coin, billed by the Royal Mint as the "most secure coin in the world", is to be introduced in 2017.

The move comes amid concerns about the 30-year-old coin's vulnerability to counterfeiting, with an estimated 45 million forgeries in circulation.

The new coin is based on the design of the old threepenny bit, a 12-sided coin in circulation between 1937 and 1971.

Jon Kay reports.
