I have collected Coach purses for years and can spot a fake a mile away.  When selling Coach purses, please do not take a picture of the serial number and post it on your auction, this is the way that others listing fakes use this information to give people the assumption that theirs are authentic. If the purse is "rare" this is a great way to spot a fake. If the seller shows a picture of the inside, none of Coach purses liners are vinyl.  Best of luck !

Buyers when you buy a Coach purse, please call Coach and verify that the serial number matches the style.
