So you’ve been researching gold and decided that it’s a foolproof investment. If its price goes up as high as predicted, you win. If its price doesn’t skyrocket, you’ll just hold onto the metal as a long-term buffer against inflation. The peace of mind that comes with an investment in precious metals is like no other. Gold coins not only help diversify your portfolio; they’re also recognized as currency across the globe.

The difficult and exciting part of your decision is deciding which kind of gold bullion coins to invest in. Mints from all over the world produce gold coins and many of them are backed by their governments. Their purity level and weight will vary, depending upon the type. It is wise to select coins that are guaranteed to be a certain level of purity. For example, the Austrian Mint produces Vienna Philharmonic gold coins that are 99.99 percent pure. They are stunning examples of 24 karat coins. The obverse side of the Vienna Philharmonic features a group of orchestral instruments, while the reverse side features the Great Organ.

Like the Vienna Philharmonic, American Buffalo gold coins are pure 24-karat gold. The obverse side features the facial profile of a Native American man, while the reverse side features the image of a powerful American bison. Each one is one troy ounce and is minted from mines in the United States. IRS rules allow you to include the American Buffalo gold coins in an IRA, if desired. Be sure to review current IRS regulations before deciding whether to include them in your retirement plan.

Your investment is an expensive one, but buying gold coins can be less costly by opting for a smaller karat. The gorgeous American Eagle bullion coins are each comprised of 22-karat gold. With Lady Liberty on one side and a family of bald eagles on the other, these coins are the epitome of the American spirit. The American Eagle coins are also allowed in Individual Retirement Accounts. The South African Krugerrand is one more example of a 22 karat coin. It was the first gold coin to offer exactly one troy ounce per piece and has a long minting history.

Buying gold coins is an adrenalin-inducing experience, because it’s so different than buying paper stocks. You can see and touch this investment. Gold coins are gorgeous by any measure. They speak to the deep, ancient core inside of all of us.
