Minted bars refer to the manufacturing process that is applied to create them. The process begins by heating gold material in a furnace until it turns to a molten slurry. During the heating process, all unwanted impurities in the slurry are removed until only molten gold of high purity is left, most often at around 99.99%. The molten gold is then poured into moulds, usually in the shape of large bars, where it cools and solidifies. The solid gold is then inserted into a mill that rolls the gold into panels with a uniform dimension. Afterwards, the gold panels are inserted into a blanking press that punches blanks out of the gold panels. The next step involves the weighing of each gold blank to ensure that it is neither underweight nor overweight and those that pass this test are then polished for them to obtain a shiny surface. The last stage involves the minting process where the gold blank is inserted into a minting press that presses its die with huge force to transfer the design from the die onto the gold blank. The result is a minted bar. The newly minted gold bar is then inspected before being sealed in a transparent tamper-proof protective package.
