The old £1 coins stop becoming legal tender on Sunday!
That means shops and supermarkets can stop accepting them, leaving you with a big wad of coins that are basically worthless.
The Royal Mint introduced the new £1 coin in March 2017 to crack down on fakes. It was estimated 1 in 30 round £1 coins were not real.
About 1.2 billion of the old coins have been returned so far, but an estimated 500 million are still in circulation.
From 16 October, the round £1 coin will be fully replaced by the 12-sided version.
If you’re handed an old £1 coin at school or at the sweet shop, you should ask for a newer one instead.
Old £1 coins can be taken to a bank after the deadline, where they will swap them for new ones.
The old £1 coins will be melted down and recycled. That’s similar to what happens with old bank notes too!
