Proof Coins
The Very Pinnacle of the Minter’s Art

Proof coins are produced to the highest quality. The modern minting process incorporates state-of-the-art technology as well as centuries-old hand skills of Royal Mint craftsmen, which are particularly important in the manufacture of the dies. Master tools are created with great care, minute details of the artist’s design being perfected by experienced engravers.

To achieve the superior quality of Proof coins, the die is sand blasted with fine particles to give a frosted finish. The surrounding table or field is then carefully hand-polished with diamond paste, a process that takes many hours and considerable skill, resulting in the mirror-like finish.

Blanks for Proof coins must be completely free from any blemishes and are polished to a brilliant shine before each one is struck individually at least three times under tremendous pressure between the carefully prepared dies. Finally, each coin is meticulously inspected to ensure that only perfect specimens are placed into protective capsules and sent to collectors.
