Hi, could you re-post here: http://forum.purseblog.com/louis-vuitton-shopping/authenticate-lv-read-rules-use-format-post-1-a-775894.html
(thread is in the LV forum, the experts are answering auth questions in that thread, add more info see first post)
p.s. don't mention selling/value questions in the authentication thread though.
Good luck.
