Time is running out for you to spend, bank or donate your old pound coins.

From October 15, nearly seven months after the new 12-sided £1 coin was introduced, businesses will be under no obligation to accept the old version, and most coin machines will only be accepting the new coin.

After this deadline you will still be able to put the old coins into your bank account, temporarily at least, but they will no longer be usable in shops.
