CHARLES becoming King will change cash, passports and the judges - and here's when it could happen.
As the Queen reigned for 70 years, we are accustomed to seeing her face and hearing her name every day.
And while that's all about to change, as Charles III takes the throne in the wake of Her Majesty's death, it won't happen overnight.
Coins and notes will go through a major change, with Charles III's face replacing the Queen's - but based on history it could take years.
The Queen's coins did not appear until 1953 – the year after her accession - and there is a long process behind creating the new currency.
The new coins and notes with the King's face will need to be designed and minted, or printed.

Then The Royal Mint advisory committee must send recommendations for new coins to the Chancellor and obtain royal approval.
Designs are then chosen and the final choices approved by the Chancellor and then the King.
Plus, the Royal Mint manufactures between three million and four million coins a day, and it’s likely to continue with the production of the current portrait and design until at least the end of the year.
That means we won’t see any new styles crop up until 2024.

The same goes for notes.
And, the current cash could continue circulating for 20 years - as the Queen's father's did after his death.
UK passports are also looking to change - but at some point further in future.
The passports will eventually start being issued with the King's name, and their wording will be changed.
Plus, Her Majesty's Passport Office will become His Majesty's Passport Office, as is the case with HM Armed Forces and HM Prison Service.
Another change will affect the the courts.
Barristers and solicitors appointed by the monarch will see their title switch from Queen's Counsel (QC) to King's Counsel (KC).
But, this too will take some time.
The British national anthem - known as God Save The Queen - will also change.

One item that won't be replaced is old post boxes with the Queen's name on them.
However, new post boxes might pop up though, now that Charles is King, but they might look a little different to current designs.
