American gold coins are coins made primarily of gold that have been minted in the United States. They have a rich history, with the first gold coins produced in the late 18th century. Popular examples include the American Eagle and the American Buffalo, which are often sought after by collectors and investors for their gold content and historical significance. These coins are typically valued based on their gold weight, known as troy ounces, and their numismatic value, which can vary depending on rarity and condition. American gold coins are also considered a hedge against inflation and a way to diversify investment portfolios.
