Why Buy Silver?

  • There is currently less investment-grade silver available on Earth for investors to buy than there is gold.
  • Today, there is only enough investment-grade silver on Earth for every person to have 1/14th of an ounce.
  • Silver is a 'miracle metal'. It is second only to oil as the world's most useful commodity.
  • Aside from being money, silver has thousands of essential industrial uses. Silver is the most electrically conductive, thermally resistant, and reflective metal on the planet that has no known substitutes.
  • For the past 30 years the world has used up more silver than has been mined, and today silver inventories are near all time record low levels.

From Wikipedia
Silver (play /ˈsɪlvər/) is a metallic chemical element with the chemical symbol Ag (Latin: argentum, from the Indo-European root *arg- for "grey" or "shining") and atomic number 47. A soft, white, lustrous transition metal, it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. The metal occurs naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such asargentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Silver has long been valued as a precious metal, and it is used to make ornaments, jewelry, high-value tableware, utensils (hence the term silverware), and currency coins. Today, silver metal is also used in electrical contacts and conductors, in mirrors and in catalysis of chemical reactions. Its compounds are used in photographic film, and dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides. While many medical antimicrobial uses of silver have been supplanted by antibiotics, further research into clinical potential continues.
