DELAYED These coins are guaranteed by the U.S. government to contain the stated amount of actual gold weight and gold content. First minted in 1986, American Eagle Gold Bullion Coins are minted according to the durable 22-karat standard. Each coin contains its full, stated weight of pure gold, so the extra weight of silver and copper is to increase the coin's durability. The size of this beauty is what we love. And if we know you like we think we do, that will be your favorite part too!
