History of Silver

Often considered the “poor man’s gold” silver has been climbing the investment and demand charts since its discovery thousands of years ago in Anatolia, now modern day Turkey. Silver’s unique properties make it ideal for thousands of applications found in every day life.

Silver is:
  • The best conductor of electricity of all metals
  • The best conductor of heat of all metals
  • The most reflective of metals
  • A powerful anti-bacterial & anti-viral agent
  • Malleable and ductile
  • Valued for its beauty
Silver is found today in mines around the world; the top producing mining countries are Peru, Mexico and China.

HISTORY OF SILVER AS CURRENCY
CA 2500 BC  
Silver first introduced into Egypt and was considered more valuable than gold.

475 BC  
China was the first country to monetize silver. 

775 AD  
“British Pounds Sterling”: in approximately 775 AD the Saxon kingdoms issued silver coins known as “sterlings”, 240 of them being minted out of one pound of silver. Large
payments were reckoned in “pounds of sterling” later shortened to “pounds sterling.”

1072  
After the Norman Conquest, the pound was divided for simplicity of accounting into 20 shillings and 240 pence or pennies.

1497  
Spanish “Pieces of Eight” were coins first struck in 1497 containing a high silver purity and weight. They were the basis of the monetary system of the Spanish Empire and were widely circulated around the world. They were accepted as legal tender in the US until 1857.

1600’s - 1900’s  
The Mexican Peso evolved into one of the world’s strongest and most widely accepted currencies due to its silver content.

1800s  
By the mid 1800s, China through trade and mercantilism, was in possession of 50% of the world’s above ground silver. The British sold opium to China in exchange for tea, silk and silver – a factor in the Opium Wars between Great Britain and China during the mid -1800s.

1930s  
Silver was used as China’s official currency until the 1930s.


SILVER APPLICATIONS
Industrial
  • As the best conductor of electricity, silver has a multiple of uses in switches, contacts and fuses in electrical appliances, automobiles and electronics such as computers, TV’s, DVD + CD players and cell phones.
  • Chemical reactions use silver as a catalyst; approximately 700 tons of silver are consumed annually in the production of plastics.
  • Mitsui of Japan is developing a catalytic converter for diesel engines using silver as opposed to platinum or palladium.
  • Billions of silver oxide-zinc batteries are produced annually for use in watches, cameras and small electronic devices.
  • Invisible silver is a thin coating of silver on double thermal windows. This coating not only rejects the heat from the sun, but also reflects internal heat inward.
  • As the most reflective of metals, silver is used in specialized optical devices, automobile windshields and for both commercial and household mirrors.
  • Very little silver used in industrial applications is re-cycled, it is consumed.

Health
  • Hippocrates, the father of modern medicine, wrote that silver had beneficial, anti-disease properties.
  • Wealthy, ancient Greeks, Romans and Phoenicians stored their wine, water and oil in silver jugs to maintain their freshness and prevent spoiling.
  • Silver compounds show a toxic effect on some bacteria, viruses, algae and fungi. Health and medical applications of silver are wide ranging and its uses include dressings and ointments for burns and wounds, anti-bacterial pharmaceuticals, coatings on hospital implements and surfaces, to name a few.
  • Silver is being used to treat wastewater and to treat streams containing radioactive and biological contaminants.
  • Silver is increasingly being used for water purification and as an anti-bacterial agent in swimming pools.
  • Clothing is being manufactured with silver impregnated fabric to kill bacteria and fungi in order to reduce disease and odour. Military uniforms, sporting wear and everyday clothing are now produced that contain this special fabric.
  • Recent research shows that silver also promotes the production of new cells, increasing the rate of healing wounds and bone.
