Gold weights and measures

Gold Bar Weights

Gold bars are made by gold bar manufacturers. They record the manufacturer name, weight and purity on each gold bar. Gold bars are sold at a low premium over the prevailing gold price. There is a large range of gold bars available to purchase internationally.

Gold bars range from 10g (some 'bars' are from 1g or less), .to 1250g (12.5kg, 400 oz) maximum for commercial trade. Larger gold bars are produced as consolidation bars at gold mining operations to ease transportation. These are supplied to refineries for refining to 999.99 parts per 1,000 or thereabouts. They are then cast into standard size gold bars.

Tables 2, 3 and 4 show a comparison of some gold bar sizes converted to grams for ease of sorting. This is not a comprehensive list.

You will note mention of minted bars there. The consensus of opinion is that Argor-Heraeus (ch) was the first (1952) accredited refiner, worldwide, to issue a range of minted bars. Now a number of accredited manufacturers produce minted bars in grammes and / or ounces.

Minted gold bar weights range from 0.3 g to 500 g, and from 1/10 oz to 20 oz. The world’s largest minted bars: the 20 oz and 500 g are manufactured by Johnson Matthey (ca).
