US gold coins are some of the most sought after coinage around the world today. With their rich history and appealing designs, they are highly desirable and have continued to increase in value over time. This is why many add a position in U.S. rare gold coins to their investment portfolios. While stocks may become worthless, these coins will never be worth less than the current value of their gold content. The fact that these coins are also backed by the U.S. government for their face value is simply "the icing on the cake".
