How can I be sure that this is an authentic coach bag?

I saw this bag and I think to buy them as birthday gift for my friend. I do not want to buy someone a gift fake .. So I need some help determining if it is a bag authentic or not. Here is a link for the http://cgi.ebay.com/COACH-RED-LEATHER-SATCHEL-SHOPPER-BAG-PURSE-9993-NEW_W0QQitemZ300227194887QQihZ020QQcategoryZ63852QQssPageNameZWDVWQQrdZ1QQcmdZViewItem bag

Despite this is not a guarantee that authentic.It Look 's bag and more, so it's not new.Do brand you see the eye bulls in relief on the upper left? This indicates that he was a coach outlet.Generally false does not make them the brand (again this is not a guarantee, but a useful tool) because they generally try to mimic the full price models.If your friend likes vintage Coach bags, I would say go for it!
