There are several ways that you can tell. Make sure that the Coach logo on the outside is centered and that each C is a mirror image, The dustbag should be chocolate brown and have the Coach Ext. 1941 written on it, The zipper should say that it is a YKK zipper, The stitching should be double stitched and of high quality, and there is a serial number in the bag that should look neatly made and be written in English and that would be verifiable on the Coach toll free customer service line.
All original bags and purses of Coach are sold in the actual store that can be found in a mall or a huge shopping center. The first way to spot a fake Coach purse is to look at the signature. The C's should be lined up perfectly to the center. Coach uses ykk zippers, so be sure to check if the markings are on the zipper.
In most cases you can look at the backside of the slider for a number and possibly a letter, such as "10D".
