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. Listed below are products with precious metal content of 1/2 oz (one half of a troy ounce, equal to 15.55 grams) of gold.
Such products with a rectangular form are known as "gold bars", and those with a circular form are known as "gold rounds". |
