The first coins bearing the official image of the new King will enter circulation in post offices around the UK from Thursday, December 8. King Charles' portrait will first appear on a 50p, with the reverse, or "tails" side of the coin, commemorating the life of his mother the late Queen Elizabeth II.
A commemorative version of the coin was released in October, and a total of 4.9 million 50p coins will enter circulation across 9,452 Post Office branches throughout December. People can get their hands on coins when they are distributed as change when customers make purchases.
Some 9.6 million 50p coins will eventually enter circulation, in line with demand. Other things including stamps and post boxes will eventually also change.
