The ABC Bullion 5oz Gold Cast Bar is produced from five troy ounces of 99.99% pure gold by ABC Refinery, one of Australia's most recognised precious metals refiners. Each cast bar is individually manufactured, resulting in subtle variations in surface texture that reflect the traditional casting process. Every bar is stamped with the ABC Bullion hallmark, weight, purity and serial number. Produced by an LBMA-accredited refinery, ABC Bullion Gold Cast Bars are recognised internationally for their quality and authenticity.
