All of mine have had a date code , newer moddels think from 08 have a hologram sticker & card too. Can u mabe get some photos of the bag , padlock ( under the lock and the chloe heat stamp on front ) pic of bag laying flat so we can see into the handles , hasp ( front of where lock attatchs to ) gold name plate ( inside ) key , both side buckles , and dust bag and tags if it has them . Lots of pix ! But needed to authenticate . Once u have them post under authenticate this Chloe thread , and some one will have a look for u !
Good luck !
