I'm with Fly on this one: both copper and nickel are non-ferrous metals which mean they can't be magnetized. If this cookware was in fact lined with nickel a magnet wouldn't be sticking to it. 409 stainless steel however, will hold a magnet. (409 has a higher concentration of carbon.) If I were to guess the actual makeup of this cookware, I would lean more towards it being copper plated stainless. Copper cookware was a "trend" way back years ago, and alot of people like the looks of it because of it's "Old World Charm," so there's still a good sized market for it. However, copper will corrode if not kept polished, so I would imagine that the manufacturer of this stuff took the best of both worlds approach and made the inner surfaces that would come into contact with moisture stainless and plated the outside with copper for the looks. Just a guess.
