Silver Eagles are the name for the United States Bullion Coin having a face value of One Dollar that started production in 1986. Because it has a face value, it is a true coin and not a medal or token. But because it contains one troy ounce of silver, its metal value will probably always be higher than its face value. It is made for those who wish to save and invest in silver that is backed by the full trust and guarantee of the United States government and its mints. They can be purchased in a variety of forms from loose uncirculated pieces to specially prepared proof editions made for the collecting public.
