Like many other mints, the Royal Mint issues bullion coins in precious metals, having much higher intrinsic value than their face value. The unusual format of thirty ounce (30 oz) gold coins are denominated as eight hundred pounds (£800) and was issued for the first time in 2017 for the 30th anniversary of the gold Britannia range.
The coins are legal tender but are not intended for circulation. They are targeted at bullion investors or collectors who appreciate these special editions as pieces of art. The coins are "one-year" types issued in parallel with smaller denominations with the same reverse designs.
