Hi! This may be my first post in Chanel. I usually lurk in Chanel and post in the BV forum. I recently acquired a medium/large black caviar classic flap w/gold hardware from 2004 w/all paperwork & documentation. I compared it to the new medium/large black caviar classic flap that I purchased from Saks a few months ago and found that there are two major differences that concern me. 1) On the button hole under the inner flap & directly above the clasp, the 2004 version has no inscription while the 2007 version is inscribed w/"Chanel Paris" 2) The 2007 version is noticeably shinier and a richer black while the 2004 version is more faded and matte. Is this due to usage? Is there any product available to restore the luster? Thanks so much!
