The new £1 coin has been in circulation for over 6 months having been introduced on March 28, 2017.
While there was much interested around the new 12-sided coin, hoarders with stashes of old £1 coins have been warned to cash them in sooner rather than later, before they are useless, and worthless!
The old coin will cease to be legal tender from October 15, meaning shops and other businesses will no longer accept them.
And the switch has raised concern that piggy banks, coin jars and savings could soon be worthless if not spent/cashed in.

Charity box collectors and those who save loose change have been urged to go through their coins and sort out the old from the new to make sure that they do not miss out.
However, it is not all bad news.
If you still have £1 coins lying about after the deadline there is no need to panic, old coins can continue to be deposited into a customer account at most high street banks in the UK, but they won’t help you if you’re short of change for the bus after the cut off date.
