Recent comments from Fed Chair Jerome ...Both the biofouling and corrosion resistance properties of 90-10 and 70-30 copper nickels appear strongly linked to the nature of the protective film formation on the alloys' surfaces. From various observations and studies, this film is complex and variable, although its importance is never in dispute. Nickels were first minted in the United States in 1866. At that time, most coins were made out of silver or gold. The United States made lower denomination coins out of pure copper. Although the nickel is silver in color, it has no silver in it. As a result, nickels lack the glitter of silver and gold and are not popular amongst coin collectors.
