Despite their silvery appearance, most nickels comprise 75 percent of what? Correct
Despite their silvery appearance, most nickels comprise 75 percent of copper, not tin, iron, or zinc. The composition of U.S. nickels is primarily copper (75%) and nickel (25%). While nickels have a silvery appearance due to the nickel content, the majority of the coin is actually made up of copper. Tin, iron, and zinc are not the primary components of nickels, with copper being the predominant metal in the coin’s composition, giving it its reddish hue and making it an essential part of the coin’s value and physical properties.
