    I do not know where you got your information. Nickel silver is a
    metal alloy of copper with nickel and often but not always zinc. It
    is named for its silvery appearance, but contains no elemental silver
    unless plated. 

    Other common names for this alloy are German silver, paktong, new
    silver and alpacca (or alpaca)Many alloys fall within the general
    term of "nickel silver". All contain copper and nickel, while some
    formulations may additionally include zinc, antimony, tin, lead or
    cadmium. A representative industrial formulation, Alloy No. 752, is
    65% copper, 18% nickel, and 17% zinc. In metallurgical science, such
    alloys would be more properly termed nickel brass. The white alloy of
    75% copper and 25% nickel used in coins, such as the United States
    nickel, is better known as copper-nickel, cupro-nickel or
    cupronickel. 

    Some nickel silver alloys, especially those containing high
    proportions of zinc, are stainless (corrosion-resistant). 

    Nickel silver alloys are commonly named by listing their percentages
    of copper and nickel, thus "nickel silver 55-18" would contain 55%
    copper, 18% nickel, and 27% other elements, most probably entirely
    zinc. A two-element alloy may be named for its nickel content alone,
    thus NS-12 is 88% copper and 12% nickel. 

    Seeing any silver anywhere? 

    I showed you mine, now you show me yours.
