How can I be sure of the purity of the products I purchase?

The Royal Mint’s bullion products are manufactured to their stated weight and purity specifications, with rigorous quality controls throughout the production process.

The Royal Mint also has a long-established system of independent testing through the Trial of the Pyx, one of the oldest forms of quality assurance in the world. Under the Coinage Act and relevant Royal Proclamations, UK coins are subject to legal requirements governing their weight, composition and specifications.

For bullion products, the precious metal content and purity are verified as part of our quality-control processes. The weight and purity of each product are clearly stated, so you can understand exactly what you are purchasing.
