2007 Topps auto question


5.00 star(s)
I recently bought a 2007 Topps Premiere Dual Auto Russell/ Quinn Rc from a member on another trade site, and when I look at the card it does not seem like normal card stock it is very thin and you can actually hold it up and see through. It has a hologram serial number sticker and looks real but hard to tell, I know that there is fakes of these floating around. Does anyone here have a topps auto from 2007 or newer and if so what is the card stock feel and look like?

Thanks , Sean
