It was quickly made to change the British national anthem from “God Save The Queen” to “God Save The King”.

But changing the image on banknotes and coins is not done in the blink of an eye. According to British newspapers Online Mail it will probably be a few years before all the notes and coins bearing the image of Queen Elizabeth go out of circulation and are replaced with the image of King Charles.

Another change is that King Charles’ view will shift to the left, while the Queen’s looks to the right, as required by Britain’s strict 17th-century monarchy tradition.

Because Elizabeth was Queen of the country for more than 70 years, most Britons have never experienced anything other than pound notes, coins and stamps bearing the Queen’s face.

Changing the throne also meant that the British passport had to change, and at least the name of the office that issued it: His Majesty’s Passport Office became His Majesty’s Passport Office.

There will also be title changes in the British judiciary, as well as badges on police uniforms and helmets.

However, the postbox with the Queen’s initials – ER for Elizabeth Regina – will remain, while the new one will be equipped with the initials of King Charles.

This also happened when King George died in 1952. Some post boxes still bear his initials even though it has been more than 70 years since Elizabeth became Queen.

based on Security the thousands of flags that have been flown outside the state police stations and on naval vessels must also be replaced with the initials EIIR (Elizabeth II Regina).
