The Royal Mint in Wales is now creating the first coins with the image of King Charles III.
It will gradually replace the ones that currently have the late Queen Elizabeth II's visage on them.
The late monarch is honoured on the back of the coin with a design that was originally on her 1953 Coronation Crown.
In honour of Queen Elizabeth, who passed away on September 8 at the age of 96.
The Royal Mint announced that 9.6 million of the coins would be put into circulation.
"He is in this instance looking to the left, his mother looked to the right. Every monarch will be looking in opposite directions to their predecessor,"
The Royal Mint just unveiled Charles' coin collection, which also honours his mother, last month.
According to The Royal Mint, King Charles "personally authorised" the collection coins.
For more than 1,100 years, the Royal Mint has produced coinage for the United Kingdom, including those used during Queen Elizabeth's 70-year reign.
According to the Royal Mint, coins featuring the likenesses of Queen Elizabeth and King Charles will continue to be used as change for many years.
