 * US nickel coins are only 25% nickel; the other 75% is copper.
 * Some hooks have a layer of nickel so that they oxidize in a slower rate.

The largest producers of Nickel are the Philippines, Indonesia, Russia, Australia, and Canada (in that order). It was recently discovered in Nigeria (Dangoma).

Nickel is found in many coins including, of course, nickels.

Nickel compounds are classified as human carcinogens. Nickel can cause allergic reactions from skin contact. This is sometimes a problem with earrings for pierced ears, but many earrings are now made without nickel for this reason.
