King Charles III Coronation commemorative Hallmark

Posted on 6th May 2023

To celebrate the Coronation of His Majesty King Charles III, the Goldsmiths’ Company London Assay Office have begun applying a new commemorative mark to items made of gold, silver, platinum and palladium. 
Sanctioned by the British Hallmarking Council, the mark - which depicts the King’s head against an oval background - was designed by Thomas Fattorini Limited, and is based on a medal by Ian Rank-Broadley FRBS. The mark can be applied by punch or laser alongside legally required components of the hallmark (sponsor, millesimal fineness, and Assay Office). 
Commemorative marks have proved popular with UK consumers since their introduction in 1934 and have been used to mark important occasions including coronations, jubilees and the Millennium. The most recent commemorative mark was issued in 2021 to celebrate the Platinum Jubilee of Her Majesty Queen Elizabeth II in 2022, and was applied to more than 70,000 items by The London Assay Office.

Jewellers, silversmiths and retailers can request the commemorative mark from 1 March 2023 until the end of 2024.
