The best gold coins for investors are those that sell at the smallest premium over the value of the gold itself. These coins include the American Gold Eagle, South African Krugerrand, Perth Mint 1-ounce Kangaroo and the Austrian 100 Coronas, according to CMI Gold & Silver Inc.
The American Gold Eagle is the bestselling gold coin in the world. Because of the high demand for the coin, however, it tends to have a higher premium cost than other gold coin types. This raises the price of the American Gold Eagle over that of other coins containing the same gold content and weight. The South African Krugerrand is also highly valued as an investment coin, primarily because it is sold at a lower premium than the American coin. Both the Gold Eagle and the Krugerrand contain 1 ounce of gold.
As of 2015, the Kangaroo has been rapidly gaining in popularity in the United States, due to its lower premium than the Gold Eagle. The 1-ounce coin also comes with a protective plastic cover that prevents scratches or scuffs, which can lower the coin's weight over time to reduce its value. The Austrian 100 Coronas have also been growing in popularity because of the lower premium charged on the coin. The growth has been limited, however, because the coin weighs in at only 0.9802 of an ounce.
