It's simple chemistry. Coins are used by people, and no matter how well you wash you still have oils and acids secreted by your skin that affect the metal.
In addition coins are exposed to air so the metal tarnishes from the effects of oxygen as well. That's why pennies turn brown and dollars go from a shiny golden color to a sort of antique brass.
