How Can I Be Sure of the Purity of My Products? | Royal Mint

When you buy coins and bars from The Royal Mint, you are purchasing from one of the oldest, most trusted organisations in the world. All United Kingdom coins struck by The Royal Mint are rigorously and independently checked for fineness and quality. Your gold and silver Bullion coins are legal tender, their weight and purity is set by an Act of Parliament and the Queens Assay. The Queen’s Assay Master role was founded in the 12th Century and resides at The Royal Mint. Today, the task of testing the metallic composition of the coins use the most modern assay techniques, and is independently verified each year in one of the oldest known quality assurance processes, known as The Trial of the Pyx. This is a judicial ceremony that dates back to the thirteenth century, and takes place annually at the Hall of the Worshipful Company of Goldsmiths in London. Throughout the year, coins are randomly selected from every batch of each denomination struck, sealed in bags containing 50 coins each, and locked away in the Pyx boxes for testing at the Trial. They are tested against Trial Plates held by the UK National Measurement Office, and a jury of leaders in the financial world and at least six assayers from the Worshipful Company of Goldsmiths confirm that the coins are within the statutory limits for metallic composition, weight and size.

Bars of 999.9 fine gold, 999 fine silver and 999.5 fine platinum are available in a variety of weights from 1 g to 400 oz. Bearing the branded RMR or Britannia logo and protected in serialised security packaging printed with a unique serial number matching the number imprinted in the bullion bar to act as a certificate.

The 400 oz gold bars used for Signature Gold™ meet the LBMA Good Delivery Standard. This internationally recognised industry standard ensures the highest levels of purity and quality.
