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.The density of copper (8.93 kg/dm 3 at 20 °C) varies only slightly with increasing nickel content (density of nickel at 20 °C = 8.9 kg/dm 3) and is 8.9 kg/dm3 for all Cu-Ni alloys specified in DIN 17 664. This aspect can also be seen in Table 7 with the physical properties of the Cu-Ni resistance alloys to DIN 17 471.
