After the death of Queen Elizabeth II, there was a lot of logistical work to be done.
The Queen's funeral and King Charles III swearing his loyalty to Parliament and the Church were some of the big things.
There is another big change that affects the entire country. It's money.

New notes featuring King Charles III will only replace notes that are damaged according to the Bank of England.
The new notes are expected to arrive in the middle of the next decade.
50p coins with a side profile of Charles are already doing the rounds, which is not the first money featuring the new King.
