good morning! and what a great, classic purse! as per our forum rules, we do not authenticate vintage items here: we suggest you take them to (for example, Chanel) to find out if they are, or not, what they appear to be. However, having said that, this style of purse was WIDELY copied as it was so popular. In my opinion, the way the edges are finished and the way it is wearing suggest that this is a copy rather than a true Chanel.
Let's see what others have to say.
if you wish to carry it once it gets cleaned up, that's your decision. but it is illegal to sell copied merchandise (contraband).
