The old round pound coin ceased to be legal tender on Sunday but some vending machines and parking meters are unable to accept the new 12-sided coin.
Approximately 400m round pounds are thought to still be in circulation with businesses such as Poundland, Aldi and Tesco still accepting them after Sunday to help customers get rid of their spare change.
We’d like to hear your stories about whether you’re still spending the old £1 coins and whether you’ve experienced any difficulty with the new 12-sided coin being accepted by some machines.
