American Buffalo Gold Bullion Coins are one ounce of .9999 fine 24-karat gold. They are investment-grade coins whose weight, content, and purity are guaranteed by the United States government. Although the coin is also legal tender, its face value of $50 is largely symbolic as the value of the gold it contains has historically been far greater.
By law, the gold for American Buffalo Gold Bullion Coins must be taken from newly mined sources in America. They are struck at the United States Mint at West Point, New York, but do not have a mint mark.
