Getting tea at the local Pret this afternoon I discovered that one of the one-pound coins I tried to use no longer had any value:
On October 15 2017, the round pound ceased to be legal tender. This meant Brits could no longer use them to make purchases in shops, supermarkets, vending machines and even car parks.
The coin was phased out over six months, to pave way for the new five sided £1 which launched last March.
Those who find themselves still in possession of any round ones will have to head to their local bank, building society or post office branch to have them traded. Most will also only agree to do so if you're an account holder.
So, I now have a souvenir round pound that cost me $1.33 at the time. Could have been worse, I suppose. Now I just have to check my £10 notes. The paper ones expire in March.
