I've never seen that style before but there are just too many red flags:
Two colors of leather PLUS a third color as a lining -
Coach usually doesn't - or didn't - throw so many colors together on one wallet. And there's no C's or logos of any kind woven into the lining which is a little unusual although a few other wallets don't either
I've NEVER seen a plain round buckle on the front of any Coach wallet OR bag.. It doesn't even look like it belongs there, and Coach wallets will always have hardware that matches the line or family they belong to. The stitching on the front just doesn't "feel" right and in the first photo it looks like the leather edging on the left side of the front flap is narrower than on the right side.
I've never seen any Coach with so many credit card slots. It looks like there are slots for 18 at least, and who carries so many cards, or ANY kind? You'd never be able to snap the wallet shut if all the slots were full.
The ONLY thing that says Coach anywhere is the stamp on the inside, and that's very easy to fake. The stamp also doesn't look like it's at the exact center of the wallet. I'd also like to see a better photo of the zipper pull and of both halves of the front snap
I'd have to say Fake.
