The Trial of the Pyx

The need for consistency in the weights and dimensions of UK coins remains of paramount importance. The Trial, which dates from 12th Century, tests that sample coins from The Royal Mint are within the statutory limits for metallic composition, weight and size. As the Trial lasts several days and the Verdict is issued 3 months later, this has been referred to as the world's longest Quality Control process!
