For a completely unrelated question (that ultimately didn't exactly get answered, but if I ever decide to post it this thread is probably not the place), I checked both Wikipedia and the official site for the composition of current Israeli coins.
And it had mentioned, among others, that 1 new sheqel coins are made of a copper-nickel alloy.
The problem? I've never heard of a copper-nickel alloy that sticks to a magnet

and all twenty or so 1 new sheqel coins I have in my collection do stick to a magnet.
I got most of them as change during my trips to Israel, so have no reason to think they should be fake.
So what is wrong here: the official site (and Wikipedia which probably copied it), my eyes, my coins, or my magnet, and just
what are 1 new sheqel coins actually made of?
