The Royal Mint is giving away 2,013 silver pennies to babies born on the same day as the Duke and Duchess of Cambridge's son.
According to traditional folklore, crossing the palm of a new born baby with silver, or offering them a silver penny, is a way of wishing them a wealthy and healthy life.
Shane Bissett, director of commemorative coins at the Royal Mint, spoke to the BBC to explain more about the coins.
Parents of babies born on the same day as the Prince of Cambridge can apply for one of the coins by visiting Facebook.com/theroyalmint.
