The Royal Family have shared an insight to the history behind King Charles III’s newly-received cypher. The social media account for the Firm posted images of the first letters bearing the new monarch’s cypher at Buckingham Palace’s Post Office on Wednesday.
The cypher bears the monogram of the monarch, which is made up of the first initial of their name and the letter “R”.
This letter denotes the Latin term for King, “Rex”, or for Queen, “Regina”.
It also incorporates the symbols showing Charles to be the third King to bear his regnal name.
A crown hovers above the letters in the new design.
A separate version exists for Scotland, bearing the Scottish Crown.
The image will be seen on letters from Government departments and on some postboxes.
The design was picked personally by the sovereign out of a collection presented by the College of Arms.
The account added that the tradition of having a franking stamp unique to the monarch can be traced back to Edward VII in 1901.

They will go on sale on November 10, featuring images of the Queen at different stages of her life.
The portraits were taken in 1952, 1968, 1984 and 1996.
They were approved by the Queen to mark her Golden Jubilee back in 2002.
The postal service has also said that stamps featuring the new sovereign will “enter circulation once current stocks of stamps are exhausted”.
New bank notes bearing the image of King Charles are “expected to enter circulation by mid-2024”, the Bank of England has said.
The portrait that is to appear on the notes will be unveiled later this year.
The Royal Mint has also said new coins will become available “in line with demand from banks and post offices”.
But all coins and notes bearing the face of Queen Elizabeth II will still be valid as legal tender.
