Inspired by the legacy of Sir Isaac Newton, Master of the Mint for nearly 30 years and one of the greatest minds of all time.

This intriguing coin forms the centrepiece of The Great British Treasure Hunt – a one-of-a-kind experience designed to take players on a journey of discovery.

At the culmination of the hunt awaits a remarkable reward. Many will join. Some will go far. But only a few will reach the final stage and be in with a chance of claiming the ultimate treasure – a 250g solid gold bar (UK residents only. Competition closes 30 March 2026).

The coin is both a keepsake and a key. Hidden within its design and packaging are layers of riddles, hidden clues and tactile finishes waiting to be explored.

Designed so that the coin can be removed from its packaging and used to solve puzzles throughout the hunt.

The obverse of the coin features the official coinage portrait of His Majesty King Charles III.
