Hello,
I have this new Isle of Man pound

I'm trying to work out what metal it is composed as. On the packaging and website I bought it from, the Isle of Man Post, its metal is described as “Nickel Brass” most likely an alloy. But on the coin order that was laid before Tynwald, the technical specification table describes it as “Nickel plated brass”

Is it most likely the “nickel plated brass” is a mistake, and it is actually the alloy?
