United States Nickel
The first nickel, the Shield nickel, was minted from 1866 until 1883, when it was then replaced by the Liberty Head nickel. The Buffalo nickel began production in 1913 as part of a program to increase the beauty of U.S. coins. Then in 1938, was the debut of the Jefferson nickel designed by Felix Schlag. By the end of 2013, it was costing more than nine cents to produce a nickel. Now the United States Mint is reasearching the possibility of lowering the cost by using less expensive metals.
