The Royal Mint of the United Kingdom is over 1100 years old. During the 18th and 19th centuries, the British pound sterling and gold sovereign from the Royal Mint and its branches across the Empire were the most circulated coins in the world. Today, the Royal Mint is the leading export mint in the world, providing coins or blanks to over 100 issuing authorities world-wide, and accounting for 15% of global coinage. Gold Sovereigns, both new and old, are still popular with gold buyers, and the Silver Britannia and large range of commemorative coins are also in high demand.
