Yep nickel plated. that explains the slight magnetic attraction. The pure nickel plating is highly magnetic but there isn't enough of it there to hold up the weight of the coin. (Also not enough to noticeable affect the weight.) And a good nickel plating can be very shiny.
It is also possible to hace a chrome plating over a nickel plating. This was often done because the chrome would adhere better to the nickel coating.
