Containing 500 grams of 99.99% pure gold, the ABC Bullion Gold Cast Bar is produced using traditional casting techniques by ABC Refinery. Each bar is individually cast before being stamped with the ABC Bullion hallmark, weight, purity and serial number. Minor variations in surface texture are characteristic of the traditional casting process and contribute to the unique finish of every bar. Produced by an LBMA-accredited refinery, ABC Bullion Gold Cast Bars are recognised by bullion dealers throughout Australia and internationally.
