After 70 years on the throne, Queen Elizabeth II had become an intrinsic part of our everyday lives. We're accustomed to seeing her portrait, profile and coat of arms on letters, in our loose change and on cereal boxes. All 29 billion coins in circulation in the UK have the Queen's head on them. The Royal Mint won't say how or when it will start issuing coins with King Charles III's head on them, but it's likely that the Queen's coins will remain in circulation for many years, and that the process to replace them will be a gradual one. Royal Mail will now stop producing Queen Elizabeth II stamps - although they can still be used on letters and parcels - and will begin the process to create new ones. Finally from tomato ketchup to packets of cereal to perfume, chances are you will have seen the Royal Arms alongside the words, "By appointment to Her Majesty the Queen" on some of your groceries or other items in your home. These are products which have been granted a Royal Warrant, meaning that the company who makes them supplies the Royal Households on a regular basis.
