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.
Noah's Ark silver coins
The Noah's Ark silver coins are Armenian bullion coins issued since 2011. They are available in various sizes with a fine weight between ¼ ounce and 5 kg in silver of 999/1000 fineness. The coin has a nominal value of 500 Dram (1 ounce) and is a legal tender in Armenia, although it is not minted there but is produced by the Leipziger Edelmetallverarbeitungs GmbH, an affiliate company of Geiger Edelmetalle. The motif of the coin remains constant, similar to other bullion coins such as the Canadian Silver Maple Leaf, the Vienna Philharmonic, or the American Silver Eagle.
