I don't know if fake Cole Haans exist - though there's fake almost anything, usually it's not worth the mass production of fake goods unless it's a really popular brand like Coach etc. That is a mighty sweet bag, though - I love the wide handle and the color.
I think you'll have to go with your gut when you see it: does the leather feel right, etc. Good luck!
