Proof coins are amongst the finest commemorative coins produced by The Royal Mint. Made with the highest care and consideration, our Gold Proof coins feature a sharpness of detail like no other.

The dies used to strike Proof coins are hand-finished to ensure that all imperfections are removed. Blanks are fed into the coin press by hand before being struck up to six times, at a lower speed and with less pressure than other finishes, to preserve the finer details of the design.

The NGC – a leading grading service for coins, tokens and medals – uses the internationally accepted Sheldon scale of 1 to 70, with 1 being the lowest grade and 70 being the highest.

In addition, the NGC uses a two-letter code before a coin’s numeric grade, describing its overall appearance and the method of coin production used. ‘MS’ refers to a Mint State coin struck for circulation and ‘PF’ refers to a Proof coin struck for collectors. ‘SP’ refers to a Specimen coin, which means it is of a better standard than a circulating coin but not in as good a condition as a Proof coin.
