The American Silver Eagle is a highly popular and iconic bullion coin produced by the United States Mint. Here is a product description of the American Silver Eagle: The American Silver Eagle is struck from one troy ounce of 99.9% pure silver (often referred to as .999 fine silver), making it a valuable investment in precious metals. The coin has a diameter of 40.6 millimeters (1.598 inches) and carries a face value of one US dollar. However, the intrinsic value of the silver in the coin far exceeds its nominal denomination. Although the American Silver Eagle is primarily sought after for its intrinsic silver content and collectible appeal, it is also considered legal tender in the United States, with a face value of one dollar.
