THE end is nigh for the old style pound coin.

If you’ve got some saved up in a jar at home, or perhaps even down the back of the sofa, you’ve not got long left before they become worthless.

The ’round pound’ will cease to be legal tender on October 15.

It has been replaced by the new design, described as the most secure coin in the world, with 12 sides and security features including a hologram.

New quid on the block: All you need to know about the new pound coin

The first ever £1 coins came into circulation on April 21 1983, replacing £1 notes – except in Scotland, where £1 notes continue to be issued in small numbers.

Since then, The Royal Mint has produced more than two billion of the round coins.

However, concerns over security – in recent years around one in every 30 £1 coins circulating have been fake – have led to the redesign which entered circulation on March 28.

Old coins can be banked or spent up until October 15.

Some will be melted down and reused to make the new £1 coin.
