Kilo gold bars are .9999 fine (99.99% pure) and contain 32.15 troy ounces each. In the metric system, a kilo is short for kilogram, the base unit of mass in the International System of Units, commonly called the metric system. The metric system is the primary weight (and measurement) system used other parts of the world.The most commonly available kilo gold bars are the PAMP and the Royal Canadian Mint (RCM) gold bars. PAMP kilo gold bars come in protective plastic cases and usually with certificates. RCM bars do not come with either protective cases or certificates. Actually, the PAMP certificate is superfluous; the real certificate is the PAMP hallmark on their gold bars. The Royal Canadian Mint recognizes this and does not issue certificates.
