Buckingham Palace staff are apparently busy processing mail at the moment. The royal family has reportedly announced that more than 50,000 letters and condolences have been received following the death of Queen Elizabeth II on September 8th. Including 6,500 on September 20 alone, the day after the Queen's funeral. Before the Queen's death, the palace received around 1,000 letters with various questions or messages every week, according to "Sky News".

In the messages now sent to King Charles III. and his family are addressed, according to the report, among other things, the following can be read: "We are thinking of you." The responsible team in the royal family apparently wants to read every message carefully and also send replies, it is said.

There has been a change in the post that comes from Buckingham Palace this week. The postmark shows King Charles' new monogram. The royal family published pictures of the first letters with the sign in an Instagram post. Several photos show the letters from the printer together with the monogram and the date September 27th.

The monogram consists of a "C" for Charles and an "R" for Rex, the Latin word for king. Inside the letters is the Latin numeral III. pictured as a sign for the third English king named Charles. The British crown is enthroned above the letters and the number.

The information contained in a monogram is always the same, but designs can vary depending on taste or in relation to coat of arms and history, according to the post on the royal family's official Instagram account. The first postmark with a monogram was in 1901 under King Edward VII (1841-1910), the Instagram post also said.
