Have a look at King Charles' Great Seal of the Realm

King Charles III has approved a brand new Great Seal of the Realm to mark his reign.

It's a special seal design that is used on things like official state documents to show that they have Royal approval.

Kings and queens first started using the seal during the reign of Edward the Confessor (ruled 1042 – 1066) during the eleventh century.

Using the seal means that the monarch doesn't need to sign every single official document in person, certain people are given permission to use it on their behalf.

A new seal is created for each monarch and they are all different.

The one created for King Charles shows him sat on a throne on one side and then has the Royal Arms on the back.

King Charles III approved his new seal at a meeting with his advisors

He approved the design for his Great Seal of the Realm at a Privy Council meeting this month.

That's where a monarch meets with special advisers, mainly made up of senior politicians.

Queen Elizabeth II's Great Seal of the Realm will be kept for historical record

While at the meeting, King Charles also struck the seal of his mother, the late Queen Elizabeth II.

This is also tradition which has been going for hundreds of years and symbolises its destruction and the change of ruler. Queen Elizabeth's seal will now safely be kept for historical record.

The approval of King Charles' Great Seal of the Realm marks the final stage of the transition to his reign after his coronation.
