Old round £1 coins will cease to be legal tender next week - but some shops will still be accepting them after the deadline.
From midnight on Sunday, October 15, 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.
People have been urged to rummage through their wallets, coat pockets, piggy banks and sofas so that they can spend them, bank them or give them to charity before this date.
However, discount retailer Poundland has said more than 850 of its stores across the country will continue accepting the coins until October 31.
And a trade association representing small shops has advised its members to continue accepting the round coins to provide a ‘useful community service’ to customers.
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.
People may also find they can still hand in the old £1 coins at the Post Office after this date.
With just a week to go, around 500 million old round pounds are still in circulation.
