This is the first time that new UK coins have been produced to mark the christening of a member of the royal family.
The Duke and Duchess of Cambridge, the Queen and Chancellor George Osborne have all given the design their approval.
A special set of coins being struck to commemorate the christening of Prince George go into production today at the Royal Mint in Llantrisant.
The Royal Mint says it has already received thousands of orders from the UK and around the world.
The Duke and Duchess of Cambridge's son will be christened on Wednesday 23 October at The Chapel Royal at St James's Palace, by The Archbishop of Canterbury.
