You wouldn't think anyone would bother to make fake COACH bags because the originals are relatively inexpensive - at least compared to other high-fashion bags such as Prada, LV, etc.  But as you know, people will do anything to make a quick buck.  Fake COACH bags are a little difficult to spot, but here are some tips based on my personal experiences and observations:

Please note: I am not affiliated with Coach - I just love their products and hate to see people get taken advantage of...

Photos:  Also please note that the photos you see to the right are NOT my photos - so they may contain bags or wallets which are NOT authentic.

1.  Signature fabric:  The "C" pattern will be off.  Except for some patterns, like the "optic" or my new favorite "scarf print," the tip of the "C" facing the other "C" should touch.  Also, the pattern should line up and start in the center of the front panel of the bag.  The seams should go straight down through the middle of the CC's, and the pattern should be aligned horizontally and vertically.  The best way to tell is to go to the COACH website and look at the real thing, and then compare it to what you're looking at on eBay and see if the pattern is different.
