Issued by the British postal agencies in Morocco, this commemorative stamp marks the coronation of King George VI and Queen Elizabeth on 12 May 1937. Adapted from the British issue, it bears the royal portraits beneath a crown and cipher “GRI,” and is overprinted “MOROCCO AGENCIES” with a denomination of 15 centimes for use in the French currency zone. Printed in rich reddish-brown, this elegant design symbolizes the transition of royal authority and the reach of British postal influence abroad. A notable collectible for specialists in British Commonwealth or overprint issues.
