22 Karat Flower Gold Coin

A gold bar, also called gold bullion or gold ingot, is a quantity of refined metallic gold of any shape that is made by a bar producer meeting standard conditions of manufacture, labeling, and record keeping. Larger gold bars that are produced by pouring the molten metal into molds are called ingots. Smaller bars may be manufactured by minting or stamping from appropriately rolled gold sheets. The standard gold bar held as gold reserves by central banks and traded among bullion dealers is the 400-troy-ounce (12.4-kilogram; 438.9-ounce) Good Delivery gold bar. The kilobar, which is 1,000 grams (32.15 troy ounces) in mass, and a 100 troy ounce gold bar are the bars that are more manageable and are used extensively for trading and investment.The premium on these bars when traded is very low over the spot value of the gold, making it ideal for small transfers between banks and traders. Most kilobars are flat, although some investors, particularly in Europe, prefer the brick shape.Based upon how they are manufactured, gold bars are categorized as having been cast or minted, with both differing in their appearance and price.Cast bars are created in a similar method to that of ingots, whereby molten gold is poured into a bar-shaped mold and left to solidify. This process often leads to malformed bars with uneven surfaces which, although imperfect, make each bar unique and easier to identify. Cast bars are also cheaper than minted bars, because they are quicker to produce and require less handling.Minted bars are made from gold blanks that have been cut to a required dimension from a flat piece of gold. These are identified by having smooth and even surfaces.To prevent bars from being counterfeited or stolen, manufacturers have developed ways to verify genuine bars, with the most common way being to brand bars with registered serial numbers or providing a certificate of authenticity. In a recent trend, many refineries would stamp serial numbers even on the smallest bars, and the number on the bar should match the number on its accompanying certificate.In contrast to cast bars (which are often handled directly), minted bars are generally sealed in protective packaging to prevent tampering and keep them from becoming damaged. A hologram security feature known as a Kinegram can also be inserted into the packaging. Bars that contain these are called Kinebars.
