Trial of the Pyx coins available from The Royal Mint, highlighting a key landmark in the history of British coins


13 December 2018
A selection of coins that have undergone the historic Trial of the Pyx ceremony are to be made available by The Royal Mint.

The Trial of the Pyx, which was first recorded publicly in 1282, is a ceremony during which samples of circulating and commemorative coins produced by The Royal Mint are selected at random and weighed for accuracy.

What is the Trial of the Pyx?

During the Trial of the Pyx ceremony jury members are presented with Pyx boxes. The coins are selected from a random selection provided by The Royal Mint and placed in copper bowls. The remainder are placed in wooden bowls and are then weighed for accuracy. The Trial is then adjourned until May to allow time for trial coins to be tested by Goldsmiths Assay Laboratory and the National Measurement Office.

The coins available for sale include:

  • a £5 Gold Proof coin celebrating the 1,000th anniversary of the coronation of King Canute
  • a £20 Welsh Dragon coin
  • a gold Proof definitive £1 coin featuring the 12-sided design adopted in 2017
  • Three different editions of The Sovereign, including a Quarter-Sovereign
  • A £20 coin celebrating the Platinum Wedding Anniversary of Her Majesty The Queen and His Royal Highness The Prince Philip, Duke of Edinburgh.
