The copper in the penny is oxidizing (combining with the oxygen in the air) to make copper oxide. Although fairly resistant to corrosion, copper does oxidize slowly in air, and when carbon dioxide is also present, its surface becomes coated with a thick green film of copper-hydroxide-carbonate. The outer surface of the Statue of Liberty is made of copper, and this compound is what gives it its green color. Visit our Cleaning Tips Page for cleaning solutions.

Tarnish is the result of a natural reaction between oxygen in the air and an alloy metal in jewelry. Alloy metals are added to increase hardness or decrease brittleness. Unlike gold and platinum, silver tarnish is created by a chemical reaction between the silver in jewelry and trace sulfur compounds in the air. See similar questions...

This is due to many factors. These include salt spray if you live near the sea or a main road, humidity and pollution. These conditions attack the lacquer on the furniture and break it down, therefore there is no protection for the brass and after a while it will become discoloured. Rings and keys can also scratch the clear lacquer coating and this should be avoided as much as possible, once the protective coating is damaged tarnishing and discolouration will start to occur.

They are usually kept on certain stock markets (like the TSX Venture Exchange in Canada) because for whatever reason they don't quite meet the requirements of the larger more mature stock markets. It is also assumed that there is a higher level of risk associated with them because of their low price which range anywhere from a half cent (.005) to $1. See similar questions...

Silver tarnish is the result of sulfur compounds reacting with the silver. Most commerial dip silver cleaners work by aggressively etching off a thin layer of silver and silver sulfide. The unfortunate side-effect of the etching process is pitting of the silver surface. With each dip cleaning, sulfur is removed from the tarnished silver surface and deposited into the cleaning solution. At the same time, the surface of the silver becomes more and more pitted.
