A nickel's melt value fell below its face value from late 2008 through mid-2010, and more recently again from late mid-2012. [114] In February 2014, it was reported that the Mint was conducting experiments to use copper-plated zinc (the same composition used for the United States 1 cent coin) for the nickel.

The US nickel coin contains 0.04 ounces (1.1 g) of nickel, which at the April 2007 price was worth 6.5 cents, along with 3.75 grams of copper worth about 3 cents, with a total metal value of more than 9 cents. Since the face value of a nickel is 5 cents, this made it an attractive target for melting by people wanting to sell the metals at a profit.
Key dates for the series include the 1939-D, and 1950-D nickels. The 1939-D nickel with a mintage of 3,514,000 coins is the second lowest behind the 1950-D nickel. The cause of the key date of 1939 stems from the new design that excited collectors the year prior, after the initial hype had settled down fewer nickels were saved.
It decided on clad coinage, with copper-nickel faces and a pure copper core, as the most desirable replacement material. Such a composition would work in place of silver in vending machines, which would not require wholesale adjustment. Copper and nickel were readily available, and the melt value of the new coins would be much under face value.
Nickel silver, maillechort, German silver, [1] argentan, [1] new silver, [1] nickel brass, [2] albata, [3] or alpacca [4] is a cupronickel (copper with nickel) alloy with the addition of zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc. [5] Nickel silver does not contain the element silver. It is named for its silvery ...
These values depend on temperature, pressure, and composition of the mineral melt. values differ considerably between major elements and trace elements. By definition, incompatible trace elements have an equilibrium constant value of less than one because trace elements have higher concentrations in the melt than solids. [1] This means that ...
Cupronickel or copper–nickel (CuNi) is an alloy of copper with nickel, usually along with small quantities of other metals added for strength, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel–copper alloy that contains a minimum of 52 percent nickel.)
