A US nickel is only 25% Nickel the rest (75%) is Copper. http://www.usmint.gov/about_the_mint/?action=coin_specifications A penny however is 97.5% zinc and only 2.5% copper.
Zinc is used as protective coating on steel, as die casting, as an alloying metal with copper to make brass, and as chemical compounds in rubber and paints, used as sheet zinc and for galvanizing iron, electroplating, metal spraying, automotive parts, electrical fuses, anodes, dry cell batteries, fungicides, nutrition (essential growth element), chemicals, roof gutters, engravers' plates, cable wrappings, organ pipes, in pennies, as sacrificial anodes used to protect ship hulls from galvanic action, in catalysts, in fluxes, in phosphors, and in additives to lubricating oils and greases. http://www.mii.org/Minerals/photozinc.html

There are numerous zinc products. Galvanized nails are one I see quite a bit. Certain types of batteries use zinc for electrodes.
It is used with copper to make brass, which is very common. It also is in vitamins because we need small amounts of it as a nutrient.
