Listing a Coach bag

Found a cute small cross body Coach at VV and attempted to list it today. Poshmark stopped the listing and ask me to certify it. I obviously can’t since I bought it secondhand. Other than listing it on FB do I have any other options? It’s not a super expensive bag (listing at $79.00) so I don’t think it’s worth authenticating.
Edit: I am a Posh Ambassador so it’s not my first listing for sure. I’ve had another Coach listed and sold without issue.

Found at a thrift store

It’s a hand made log cabin pattern in the most incredible colors I’m obsessed.
Adding another picture post wash in comments.
