Containing 1.177 troy ounces of pure 22-carat gold in a 36-mm coin, it sits at the top of the sovereign-family pyramid and is one of the most prestigious modern gold collector pieces. This guide covers specifications, historical and modern issues, realised auction prices, and how the quintuple sovereign compares to the 1 oz gold Britannia for UK gold investors.
