Gold bars have captivated people throughout history. The earliest types of gold bars were ingots produced when molten gold was poured into molds. Today, gold bars are still sometimes referred to as ingots. They are created in various sizes: from one ounce to 400 ounces. Large bars are typically traded on major exchanges but are more difficult to trade in secondary markets because of their value and their size. As a financial asset, the most common purchases include one-ounce and 10-ounce gold bars.
The designs of gold bars vary greatly. They can be plain and smooth or meticulous and detailed. Just about all gold bars will display the amount of gold, the purity and the issuing company.
Some of the companies that manufacture or hallmark gold bars include Johnson Matthey, Credit Suisse, ProduitsArtistiques de MétauxPrécieux (P.A.M.P.) and Englehard.
