Aruba 5 cents

Admins, please check that the composition of the Aruban 5 cent is really aluminum, and not nickel-plated steel as my specimens indicate.

Not that I am Admin, but I agree that it is not Aluminium, as per photograph below. All coins for Aruba started in 1986 and went from KM#1 to 6 and all were made of the same NiCS which must stand for Nickel Coated Steel like you said.
