Master tools and dies

Perhaps the most distinctive element of the Royal Mint Museum is the collection of some 30,000 master tools and dies. Apart from a handful of medieval coin dies, these run in unbroken sequence from the middle of the 17th century and relate to the coins and medals struck by the Royal Mint since that time.

Dies are used at the final stage of production to impress the design on a coin or medal, while the term master tools encompasses the preliminary tools such as reduction punches, matrices and working punches required to make the dies.
