It is the nickel in some silver jewelry that reacts with your body chemistry to turn your skin and the jewelry black. .925 Sterling Silver, such as that offered by Tiffany and Silpada, contains no nickel. .925 sterling silver is 92.5 pure silver, with only 6.5% copper added for stablity.
True sterling silver will not leave green marks on your finger. Sterling from North America is fine silver ( .999 pure) a .925 % and copper makes of the rest of the alloy.

Yes. Silver tone jewelry will turn your finger green because the metal under the silver tone is probably a brass which contains copper. It is the copper that turns your finger green.
The acidity in skin has tendency to cause silver to turn black or green. This is a corrosive agent that can be cleaned with a quality silver cleaner.
When you heat nickel nitrate, it decomposes to form nickel oxide, nitrogen dioxide gas, and oxygen gas. The reaction is represented by the equation: [ Ni(NO_3)_2 \rightarrow NiO + 2NO_2 + 1/2O_2 ]

One way to test a coin for real silver is to use a silver testing kit that includes nitric acid. You can apply a drop of acid on a small inconspicuous area of the coin and observe the reaction. If the coin is made of silver, it will turn a creamy color. Alternatively, you can use a magnet to check for magnetic properties, as silver is not magnetic.
