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.
The Royal Mint has celebrated moments of national significance for over 1,000 years and it was felt appropriate to produce the first-ever set of Royal christening coins to mark the christening of our future king.
The classic design of these coins was inspired by the symbols and images from the silver gilt lily font, which has traditionally been used for every Royal christening since 1841.
Silver is closely associated with new born babies, as crossing the palm of a new born baby with silver is a way to wish them wealth and good health throughout their life.
