The first coins bearing the official effigy of the King will appear in circulation in post offices around the UK from Thursday.
The King’s portrait will first appear on a 50p, with the reverse, or “tails”, side of the coin commemorating the life and legacy of Queen Elizabeth II.
A commemorative version of the coin was released in October, generating record visitors to the Royal Mint’s website in the 24 hours following.
A total of 4.9 million 50p coins will enter circulation across 9,452 Post Office branches throughout December.
