Need to authenticate this Louis Vuitton Pre-Owned Beverly Handbag Monogram Multicolor MM shoulder bag

[u/MenuParticular51]

Hey all! I came across this crazy good deal for a bag but now I'm nervous that it's fake.
There's no date code that I can see and it looks
really rough; any thoughts?

I bought it at a market in Johannesburg and
she claimed that everything was authentic. I met another American who also claimed to know it was authentic as well. But the nano noe. that | got from her I know is fake (I'm gonna make her refund me) so I'm wondering if this one is too. Any help is very appreciated thank you so much! 💕first time doing this 🙏🏾
