Need Some help with w560 Authenticity
 

I picked up a lot of w560's this afternoon... All the cards in lot lot are pretty rough (creases/miscut/writing etc...). Anyhow, before purchasing them I did some research via my handheld and found that the authentic versions were printed on a multi layer stock where the front was a different color than the reverse... All of the ones I purchased have a pinkish orangish front and a grey back... with that & the smell of oldness that each possesed I felt somewhat comfortable in making the purchase...

In anycase I was hoping to get some opinions from the resident experts, before I advertise any for sale... I have attached photos of a few examples... pardon the poor photos as they are coming from my blackberry

Thanks in advance for your help!
