Sac à main Chanel mini Timeless Black

Hello,

I sell this authentic handbag Chanel mini timeless that was owned by my mother and it seems like she almost never used it.
We cannot find the authenticity card and the Chanel shop does not make expertise or duplicate invoice.
But you can see at the bottom of the bag a tag with the serial number.
She did not wear it much as you can see on the photos, there is still a plastic protection on one zip.
