Gold Bullion: Stamps, Hallmarks & Sizes

Oh, how we would all love to have a secret horde of gold bullion and bars hidden in the basement of our home! The very foundation of wealth, gold seems to glow like a magic material and one of its amazing properties is that gold does not oxidise at any temperature. If you are planning to include gold in your investment portfolio, here is some background information on the hallmarks and stamps found on gold of all sizes.

Gold Purity

Of course, gold can vary in purity; from 9k right up to 999.9 pure, which is a global standard. For jewellery, gold is usually 9k, 14k or 18k, which is more suited to daily wear than 24k gold, which is soft and malleable. For investment purposes, you would stick to the top grade, which is 999.9 and by registering with a leading gold bullion dealer, you can use their secure market connection and trade in real time.

Gold Bar Markings

By law, a gold bar must contain certain information by marking:

  • Characteristic
  • Weight
  • Manufacturer
  • Origin
  • Serial number

On a 1kg bar of gold, the maker’s stamp would be on the top, with the country of origin next, followed by the weight and the assayer’s stamp and finally, the serial number for identification purposes.

Various Forms Of Gold

Gold comes in many formats, such as:

  • Gold ingots
  • Gold bars
  • Gold coins
  • Gold jewellery

Major gold bullion dealers trade in 1kg bars, which are 999.9 pure, yet bar sizes range from 1 gram to 1 kg, in both imperial and metric weights. Due to the ease of creating gold ingots, they come is a wide range of weights and every ingot would have all the required stamps, regardless of size.
