King Charles III Coronation Centres 25mm or 50mm
The Official King Charles III Coronation Design Inserts are available in two different diameter sizes:
The 25mm King Charles Centres will fit all 40mm and 50mm medals and can also be used in some 70mm medals and 25mm badges as well as the Kings Coronation Spoon
The 50mm King Charles Coronation Centres can be used in most 70mm medals
You can, of course, use these centres for whatever you want to put them on as they have a self adhesive backing
