Now we have a new King, one of the biggest changes people may begin to notice in their day-to-day lives will be the cash in their wallets.
It is expected that notes and coins in circulation with the Queen's portrait will gradually be replaced by new printed and minted notes and coins with Charles' image, but the Bank of England has refused to give details at present, saying an announcement regarding existing banknotes will be made once the period of mourning has been observed.
The Bank of England has already reassured Britons that current bank notes featuring the image of the Queen will continue to be legal tender, but with over 4.7 billion Bank of England notes in circulation, worth about £82 billion, it's unlikely to be a quick process, according to Thisismoney.
