The round pound is on its way out, and in just for few short days it will disappear from our currency.

After the deadline passes, the 12-sided coin will be the only form of £1 we will find in our pockets.

But some supermarkets and retailers will still accept the round pound as payment after the deadline.

Here is everything you need to know.

When does the round pound cease to be legal tender?

The round pound will cease to be legal tender on Sunday, October 15, after this date businesses can stop accepting them as payment or give them out as change.

Currently the 12-sided coin and the round pound are in co-circulation, this means that they are both accepted by banks and stores. However by midnight on Sunday this will no longer be the case.

Can I put my round pounds in the bank?

In short, yes. But you’ve only got until October 15 to do this.

Unlike old paper notes - which can be posted to the Bank of England at any time - once the deadline has passed you will not be able to spend or bank your round pounds.

A poll taken by the Royal Mint estimates that one in three households have some stashed away in savings jars and piggy banks - which means there’s roughly around 9 million households across the country with round pounds in their possession.

Many of the old round pounds will be melted down to make the 12-sided ones.

Which retailers will still accept them after the deadline has passed?

Tesco, Aldi, Iceland and Poundland will still accept round pounds after October 15.

Iceland will accept the old £1 coin until Tuesday, October 31. This will apply to all Iceland and The Food Warehouse stores in the UK.

Meanwhile, Tesco has said it will still accept the coins for an extra week after the October 15 deadline.

Speaking to The Guardian, an Aldi spokesperson said: "To make the transition as easy as possible for our customers, we will continue to accept the old £1 coins as payment across our stores until 31 October.”

Poundland will also be accepting the coins until the end of the month.
