Why 22 karat?

The small amount of silver and copper makes the coin harder and more scratch-resistant than pure 24-karat gold. Because the coin is slightly heavier overall, it still contains exactly one ounce of gold. You're not getting less gold than in a 99.99% coin of the same size.

Why it's allowed in an IRA

IRA gold normally has to be at least 99.5% pure. The Gold Eagle is below that, but the law specifically permits gold coins minted by the US Treasury under the relevant statute, so it qualifies. Similar 22-karat coins from other countries, such as the Krugerrand, do not. See our IRS-approved list.

What you'll pay

Gold Eagles usually cost more over spot than foreign bullion coins like the Maple Leaf, because of demand and the US Mint's pricing to its dealers. Fractional sizes cost more per ounce than the 1 oz coin. Compare the premium per ounce before choosing, and check our gold coins guide for alternatives.

Design change in 2021

The US Mint introduced a new reverse design in 2021, often called Type 2. Both designs contain the same gold and are equally IRA-eligible. For investment purposes, the design doesn't matter.
