DEFINITELY keep the grey patent - I would return the the other two. Unless money isn't really an object, then I'd also keep the atlantic b/c it really is a fun bag! But I also agree that if it's been in your closet that long, it's probably time to return it!
Edit: I posted before I read your entire thread! Glad you decided to keep the grey, I think it is so beautiful! And probably a good choice to return the atlantic!
