The death of the Queen yesterday ended her 70-year reign over the UK and the commonwealth realm, making her the longest-serving monarch in history.
Because her reign was so long, the Queen is very much ingrained into British culture - not just as a member of the Royal Family but in things we see every day, such as our stamps, currency and passports.
Changing all of these to reflect the new King, the Queen's eldest son Price Charles, won't happen immediately as it's likely to take several years.
Banknotes that feature the Queen will still be legal tender, as the Bank of England says replacing them to feature the King will take at least two years, with coins taking longer.
Here's what will happen to other royal symbolism on our stamps and passports following the death of the Queen.
What will happen to our stamps?
Royal Mail stamps, which currently feature a picture of the Queen, will still be valid.
In a statement, Royal Mail has said: "Following the passing of HM Queen Elizabeth II, Royal Mail has confirmed that stamps bearing the image of Her Majesty Queen Elizabeth II remain valid for use.
"These include definitive stamps – regular ‘everyday’ stamps – and special stamps.
"As previously announced, following the introduction of barcodes to everyday stamps, these stamps remain valid until the end of January 2023."
It's likely that the Post Office will change stamps gradually, with an image of the new monarch.
The Queen's first picture to appear stamps was taken by Dorothy Wilding in the weeks following her ascension to the throne, and were approved some weeks later.
This was used until 1967, when it was replace by the iconic sculpted head image by Arnold Machin.
Royal Mail postboxes, which also feature the Queen's royal cypher ERII, will not be changed.
The statement from Royal Mail continued: "Post boxes already in production or being prepared for installation will also retain the insignia of Queen Elizabeth II."
What will happen to our passports?
People may be wondering if their passports are still valid following the Queen's death.
All UK passports currently read: "Her Britannic Majesty's Secretary of State requests and requires in the name of Her Majesty all those whom it may concern to allow the bearer to pass freely without let or hindrance and to afford the bearer such assistance and protection as may be necessary."
It's likely that new passports will need to change to reflect the King's pronouns.
However, My London reports that passports will only need to be updated once they've expired, so there is no need to purchase a brand new one.
This is similar to when the UK's new blue passports were issued - the burgundy ones are still valid, as long as they are within the expiration date.
