New money is issued in the UK.

The Bank of England has released new paper money featuring King Charles III, making him the second monarch to appear on UK banknotes after his mother, Queen Elizabeth II. The new £5, £10, £20, and £50 bills will feature Charles' portrait, while the rest of the design will remain the same. The old banknotes with Queen Elizabeth's portrait can still be used, but as they wear out or the demand for paper money increases, new ones with Charles' likeness will be printed and put into circulation. The process follows guidelines set by the royal family to reduce waste, cost, and environmental impact. The king was presented with the first of the new banknotes at a ceremony, and some people are eager to obtain bills from the earliest batch, which will be more valuable to collectors.
