Explore our range of Kilo Silver Britannia Coins, featuring some of the largest and most prestigious silver coins issued by The Royal Mint as part of the Britannia series. Struck in .999 fine silver and weighing one kilogram, these impressive coins represent the pinnacle of large-format Britannia issues, combining substantial precious metal content with iconic British design.

Each coin contains 1,000 grams (approximately 32.15 troy ounces) of pure silver and carries a £500 face value. The designs feature the classic Britannia motif symbolising strength, integrity and maritime heritage, alongside the portrait of the reigning monarch. Modern issues incorporate advanced Royal Mint security features such as micro-text, latent imagery and surface animation, enhancing both visual appeal and authenticity.

Kilo Silver Britannia coins are produced in extremely limited quantities and are highly sought after by collectors and investors due to their size, low mintages and premium presentation. Available in both bullion and proof formats depending on the year, many examples are supplied in official Royal Mint packaging with certificates of authenticity, with select coins professionally graded by PCGS or NGC.

Whether you are building a high-end Britannia collection or searching for one of the most impressive modern British silver coins ever struck, discover our selection of Kilo Silver Britannia Coins at The London Coin Company .
