The British Royal Mint Selects Stack’s Bowers Galleries to Sell

The Historic Trial of the Pyx Coins

This special auction by Stack’s Bowers Galleries will feature an impressive selection of gold, silver, and platinum coins tested in the 2023 Trial of the Pyx.

Stacks Bowers Galleries is honored to once again partner with The Royal Mint of the United Kingdom for an auction sale of historic British numismatics. Presented in February 2024 will be a special auction of coins that have been tested and evaluated as part of the annual Trial of the Pyx, an ancient and rigorous evaluation ceremony with origins that stretch back over seven centuries. This is the first time these Trial of the Pyx test coins will be presented in a public auction, and it is sure to draw attention from collectors and investors around the world.

The Trial of the Pyx is conducted annually by The Royal Mint to ensure the accuracy and integrity of the nation’s coinage. Dating to 1282, it is one of the oldest judicial ceremonies in England. During the trial, a selected panel of expert assayers from the Goldsmiths’ Company, an independent organization, examines a sample of coins produced by The Royal Mint the previous year. The coins are tested for weight, diameter, composition, and design, verifying their compliance with legal standards set by the Coinage Act. The findings are reported to the Royal Remembrancer, who presides over the trial on behalf of the Crown. The trial concludes with an announcement of the verdict, confirming the quality and accuracy of the coinage.

Lucy Mackenzie, Director of Collector Services at The Royal Mint said: “We are delighted to continue our partnership with Stacks Bowers Galleries with this next auction of Trial of the Pyx coins. The Trial of the Pyx is one of the United Kingdom’s longest-established judicial ceremonies, ensuring the quality and accuracy of our coinage since 1282.

This offering represents a union of America’s most prestigious and accomplished numismatic auctioneer with the United Kingdom’s oldest continually operating company and the second oldest mint in the world. The Royal Mint was founded over 1,100 years ago, responsible for the coinage of England and, thereafter, the United Kingdom, and has since grown to become the world’s leading export mint, respected for the exceptional quality of their collectible and bullion coinage. Stack’s Bowers Galleries was founded in New York City in 1933 and has built a reputation as America’s leading auctioneer of rare coins over the past century, handling some of the greatest rarities and most valuable collections ever sold. Together, these historic firms are delighted to present these test pieces from the 2023 Trial of the Pyx to collectors.

This joint-effort between Stack’s Bowers Galleries and The Royal Mint comes on the heels of a similar partnership between the two organizations in August 2023, where a special auction sale of Royal Succession Sovereign and Britannia coins realized more than $5.1 million in total prices, including a Gold 1 Ounce 2023 Britannia that sold for $50,000.

Stack’s Bowers Galleries is honored to have been selected by The Royal Mint to auction these special Trial of the Pyx test coins and is excited to present them to the collecting community in February 2024.
