How do you tell if juicy couture purse is a fake?

Well to tell if a Juicy Couture purse is REAL the ID digit should have 9 id numbers also I collect juicy purses and if it was made after 2005 the zipper should have a heart with a "J" in the middle. It wil also have real leather. If it is fake it will have rough coarse leather.

..... I on the other hand know mine is not fake it has the id number on the tag and also says made of 100% cowhide leather but i know its made before 2005, the colour is worn a bit, would it still be worth anything?
