Kilo bars are popular for large investors because they are normally traded at a low premium above the market value of their gold content and each bar is etched with a unique serial number, aiding in the proof of provenance and ownership.
While almost all kilo bars now have a flat rectangular shape, traditional kilo bars were in the shape of a brick and are still traded in some countries. The typical length ranges from 110-120 mm, and thickness 8-10 mm. Approximately the same size as a typical iPhone. This rectangular shape has been adopted as the unofficial international standard since the 1960s and is easy to stack and carry. Many refiners supply dealers with a certificate for each bar, which will show its purity ( .9999 and other relevant data)
Manufacture
The traditional method of making bars is to cast (pour) liquid gold, which has been melted at 1064 Degrees C in a crucible, into a mold with the appropriate dimensions.
Minted bars are normally cut from a cast bar that has been rolled to a uniform thickness. The cutting is usually done with a die to create blanks that have the required dimensions and weight. All the surfaces (top, base and sides) are smooth and even. Markings are then applied by a minting press like a coin, or sometimes etched.
Our clients find this their most preferred product, due to its convenient size, and that it is one of the most liquid of bar sizes internationally.
