The Britannia is the most popular gold coin produced by the British Royal Mint. It was first introduced in 1821. This beautiful bullion coin on its obverse reveals the image of Queen Elizabeth II, Queen of United Kingdom in the crown, and the nominal value of the coin (£ 100). The obverse of the coin is modified in every odd year of issue, in order to emphasize the uniqueness of this coin. The reverse of the coin remains unchanged and represents a traditional Britannia figure armed with a shield, an olive branch and a trident. In her surroundings we will find information with the name, metal finesse (999.9 fine gold) and weight of gold (1oz). The reverse was designed by Philip Nathan, and the obverse was done by Jody Clark. In the 2017 the coin has been additionally secured by the lines in the background. The Royal Mint is one of the oldest and most developed European mints. The Royal Mint produces coins and medals for about 60 countries around the world. It also has exclusive use for the production of pounds and state decorations in the United Kingdom.
