It will take around two years to withdraw and replace the 4.5 billion Queen Elizabeth II banknotes in the UK with those featuring King Charles, according to the Guardian. However, plans to renew the pound have not been finalized, according to the Bank of England. “The Queen will continue to be legal tender. A further announcement regarding existing Bank of England notes will be made once the mourning period has been observed,” it said in a statement on Thursday. In Australia, the coins were likely to depict Charles III with his face turned to look to the left, the opposite of coins with his late mother facing right, according to the Canberra Times. It will reportedly take two years for Queen Elizabeth II banknotes to be withdrawn and replaced. The obverse tradition, in which a new king faces the opposite direction from his predecessor on the coin, began under Charles II in 1660, according to the report. According to reports, coins featuring Elizabeth would be circulated alongside those of her son Down Under. In Canada, $20 bills and coins will continue to feature the queen until Prime Minister Justin Trudeau’s government decides to introduce her successor, Bloomberg reported.
