How much a gold bar is worth depends on its weight, fineness and brand, as well as the current gold price. Some types of bar, like the 3.75oz ‘ten tola’ popular in south-east Asia, can be worth much less per gram of fine gold than others, such as gold kilobars cast by big-name Swiss refineries.
How much this gap matters between what different gold bars are worth depends on whether you are investing or collecting. Over 30 types of gold bar are in circulation around the world, and the most cost-effective by far is the 400oz (12.4kg) ‘Good Delivery’ bar, cast by LBMA-approved refiners, and stored inside specialist vaults. These gold bars are worth much more than any other type per gram of fine gold.
