Commemorative jewellery depicting royalty was usually produced after the monarch's death, but was occasionally available during their lifetime, to be worn as a demonstration of loyalty.Many examples have hinged lids: supporters of the Royalist cause, who wished to keep their allegiance secret, probably wore these during the Commonwealth under the rule of Oliver Cromwell.
