The Royal Mint of the United Kingdom, which makes the country's circulating coinage, is also very active in the bullion coinage space and issues many bullion coins which are legal tender.
Additionally, it also makes bullion which is not legal tender and is targeted at investors and not at coin collectors. The format of four hundred ounces of gold, due to its price, is targeted at institutional investors.
These products are rectangular in shape and are known as "gold bars"; they are cast, as their size is not suitable for regular minting techniques. |
