The King’s Coronation Mark

The British Hallmarking Council announced the design of a commemorative hallmark to celebrate the coronation of King Charles III

Based on a medal by Ian Rank-Broadley FRBS and using artwork supplied by Thomas Fattorini, the mark depicts the King’s head against an oval background - as shown above struck into aluminium during our test process. It can be applied to gold, silver, platinum or palladium items, by any of the four UK assay offices. The approval process involved the assay offices considering a selection of possible designs and submitting two to the British Hallmarking Council which chose the design depicting the King’s head.

Will Evans, General Manager said, “The London Assay Office is proud to offer this historic mark to jewellers and silversmiths until the end of 2024. The skill of our engineers has been pivotal in realising this important moment. Their decades of precision engineering experience and attention to microscopic detail has led to the creation of some truly beautiful metal punches and digital artwork for laser application. Seeing a London hallmark reach the end-consumer is always significant, and no more so than when it incorporates a commemorative mark to signify a key moment in national life.” 

The King’s Coronation Mark will be an optional mark. Punches will be available in sizes 1mm to 6mm and the minimum size will be 1mm for punches, and 0.75mm for laser. The King’s Coronation Mark can be placed anywhere viable on the item being hallmarked, not necessarily next to the statutory hallmark, and can differ in size from the compulsory component marks. It can be made as large as is practically possible on the item being submitted, and can be used with or without the current Date Letter mark.
