Capturing The Duke of Cambridge in a candid pose of determination, gazing ahead to the future, Thomas T. Docherry, a product designer and engraver at The Royal Mint, has created the reverse design celebrating this milestone birthday. Coincidentally, Thomas also turned 40 in recent months, which forges an endearing connection between the designer and The Duke of Cambridge.

Entering his fortieth year, The Duke of Cambridge has evolved into his senior role with seamless confidence. To commemorate this milestone birthday, The Royal Mint has struck a £5 coin - one we may look back on with fondness in years to come.
