British Guinea Gold Coins

Browse our range of British Guinea Gold Coins, featuring authentic historic gold coins struck by the Royal Mint between 1663 and 1813. The Guinea was the principal gold coin of Britain before the introduction of the modern Sovereign and remains one of the most important and iconic coins in British numismatic history.

The Guinea coin was first introduced during the reign of Charles II and was originally valued at twenty shillings, though its value later fluctuated with the gold market before being standardised at twenty-one shillings in the early 18th century. Guineas were struck in several denominations, including Full Guineas, Half Guineas, Third Guineas and Two Guinea coins, spanning multiple monarchs such as George I, George II and George III.

These historic gold coins were the foundation of Britain’s gold currency system prior to the Great Recoinage of 1816, when the Guinea was replaced by the modern Sovereign. Today, Guinea gold coins are highly sought after by collectors due to their historical significance, artistic design and rarity.

Our selection includes certified examples graded by PCGS and NGC, covering a wide range of monarchs and denominations. Many coins feature exceptional detail and preservation for their age, making them highly desirable within the pre-Victorian gold coin market.

Whether you are searching for a George III Full Guinea, a rare Half Guinea or an early Charles II issue, our British Guinea Gold Coin range offers some of the most historically significant gold coins available to collectors.
