Gold is available for investment in the form of bullion and paper certificates. Physical gold bullion is produced by many private and government mints both in the USA and worldwide. This option is most commonly found in bar, coin, and round form, with a vast amount of sizes available for each.

Gold bars can range anywhere in size from one gram up to 400 ounces, while most coins are found in one ounce and fractional sizes. Like other precious metals, physical gold is regarded by some as a good way to protect themselves against the ongoing devaluation of fiat currencies and from volatile stock markets.

Buying gold certificates is another way to invest in the metal. A gold certificate is basically a piece of paper stating that you own a specified amount of gold stored at an off-site location. This is different from owning bullion unencumbered and outright because you are never actually taking physical ownership of the gold. While some investors enjoy the ease of buying paper gold, some prefer to see and hold their precious metals first-hand.
