Old round pound coins will cease to be legal tender next week - but some shops will still be accepting them after the deadline.

From midnight on Sunday, the round pound will lose its legal tender status, meaning stores cannot hand out old pound coins as change and can refuse to accept them as payment.

However supermarket giant Tesco has confirmed it will continue accepting old round pound coins after they cease to become legal tender.

It follows a similar announcement by discount retailer Poundland, which will be accepting round pounds until October 31.

Around 500 million old round pounds are believed to still be in circulation.

The new 12-sided pound coin, which resembles the old threepenny bit, entered circulation in March and boasts new high-tech security features to thwart counterfeiters.

Major banks have said that while they encourage customers to allow enough time to hand in their old coins, they will continue to accept deposits of round pounds from their customers after October 15.

And people can also deposit the old coins into any of their usual high street bank accounts through the Post Office - even after October 15 - "until further notice".

The Post Office is also taking part in Pudsey's round pound countdown - collecting old round £1 coins for BBC Children in Need.
