What's happening to old £1 coins?

From 15th October you won't be able to spend the old style £1 coins in shops. A new £1 coin was released earlier this year which has 12-sides, instead of round and also has lots of new security features to make it difficult to copy. Ricky's been to the Royal Mint in Wales, where all of our coins are made, to find out what happens to the old ones.
