    Cupronickel

    I prefer to write 75Cu25Ni to designate the alloy but that doesn't appear to be used much in numismatics

    I like Oldhoopster's way of describing the alloy more precisely, but otherwise why not make it short so I like to use 'Cu-Ni' which is shorter to write.

    Copper-Nickel

    This could actually be a can of worms.

    CN Indian Head/FE cents.

    Our "nickel" is actually a CN alloy.

    Most coins we call copper nickel are "clad", layers of copper and CN alloy.

    Hadn't really thought about it but CN works for me.

    Just clad for me - as long as it gets the "NOT SILVER" message across I'm good with it!
