1. Introduction
At Cheshire Gold Xchange, we love British Sovereign coins! These are one of the most widely traded and recognisable gold coins globally, and huge favourites in the UK due to the capital gains tax benefits they attract. The Sovereign coin was first minted in 1489 under the reign of King Henry VII, the modern Sovereign as we know it was first introduced in 1817 following the Great Recoinage. These gold coins quickly became a symbol of economic power held by the British Empire. Sovereign served as legal tender and a coin traded globally.
The full Sovereign coin weighing 7.98grams has a legal face value of £1.00, a half Sovereign £0.50, and a quarter sovereign £0.25. However, with these legal face values the coins actual market value is a lot higher due to its gold content and collectible appeal. Sovereign coins are now priced on their gold content, and numismatic value ie. rarity, age, and condition. They remain as legal tender in the UK but due to their higher value in gold content they are not actively used as tender.
2. Mint Marks and Locations
Mint marks on British Sovereign coins are small letters that indicate the location where the coin was minted. The mint marks are located on the reverse of the coin, below the main design. They are crucial for identifying a coin’s origin and can greatly affect its rarity and value.
Classic St. George and the Dragon Design (Modern Sovereigns): The mint mark is located on the ground, just above the date, beneath the horse’s hoof in Benedetto Pistrucci’s depiction of St. George slaying the dragon.
Shield Design (Used on Early Sovereigns and Special Editions) The mint mark is found in the decorative scrollwork or directly below the shield on the reverse side.
They are crucial for identifying a coin’s origin and can greatly affect its rarity and value.
