What is Bullion? Bullion refers to precious metals like gold and silver, valued primarily for their weight and purity. It’s typically bought as coins or bars and traded close to its intrinsic metal value. This is irrespective of the coin's condition, unlike proofs and uncirculated products, that may have a value above the intrinsic price.

History of Britannia

Today, the Britannia is the UK's most popular 1 oz bullion coin, manufactured by The Royal Mint since 1987 in gold and since 1997 in silver. For more information on UK Britannia bullion coins, you can read our blog, which details the history of the Britannia since its adoption.

What Is Capital Gains Tax?

Capital Gains Tax (CGT) is a form of levies imposed on the profit garnered from the sale of assets, such as real estate, investments, and collectibles. In the United Kingdom, the present CGT allowance is £3,000 per annum per individual, which implies that one can earn up to £3,000 from the sale of assets prior to being subject to CGT.

For UK residents, bullion coins which are UK legal tender pound sterling coins are exempt from capital gains tax (CGT).
