St George is a familiar figure on British coinage, first appearing on certain gold coins issued during the reign of Henry VIII.
Shane Bissett, director of commemorative coin and bullion at the Royal Mint said: "The choice of the St George design to honour Prince George's birthday is an apt one - the name George has long had links with the British monarchy and its coinage, there having been six kings of that name during the Royal Mint's 1,000 year history.
"The choice of a silver £5 coin is significant too as the tradition of crossing the palm of a new born baby with silver is a way to wish them wealth and good health throughout their life."
Both George's birth, his christening and his first birthday were marked with commemorative coins.
Earlier this month the Royal Mint unveiled a special commemorative coin to mark the christening of his little sister, Princess Charlotte.
Featuring two harp-playing cherubs surrounded by swags of lilies, the £5 silver coin was the second made for the two-month-old princess.
That coin was the work of engraver John Bergdahl, who also created Prince George's commemorative christening coin in October 2013.
More than 2,000 commemorative silver pennies were given to babies born on the same day as the little princess.
The silver £5 coin issued by The Royal Mint to mark the birth of Prince George in 2013 was so popular that its mintage of 10,000 coins sold out within days.
