Silver
Silver is a chemical element with symbol Ag (from the Latin "", derived from the Proto-Indo-European "h₂erǵ": "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
American Silver Eagle
The reverse was designed by John Mercanti and portrays a heraldic eagle behind a shield; the eagle grasps an olive branch in its right talon and arrows in its left talon, echoing the Great Seal of the United States; above the eagle are thirteen five-pointed stars representing the Thirteen Colonies. The reverse is inscribed with the phrases "UNITED STATES OF AMERICA", "1 OZ. FINE SILVER~ONE DOLLAR", and "E PLURIBUS UNUM" (on the banner that the eagle holds in its beak), as well as the mintmark if applicable.
