I have enclosed best pics I can. serials numbers engraved on magnetic snap closure read on one side of circled closure P.A.T. 90816- other side of circle snap closure K-SOUNG. CC's on intacted change purse inside, chanel label w/ circled R, cc on metal ball holding leather tassel. and large CC on front of purse. thats all I really have to go by, and know NOTHING about authenticate chanel purses, so im hear asking for your help, all replies are greatly appreciate to make me understand a authenticate from a replica.
