It's never really possible to say a wallet is genuine just from photos. I'm not seeing any obvious red flags although the stitching colors aren't quite the same as in Coach's photos. You have to actually handle a Coach wallet to be sure it's real.
If you bid, be sure you pay with a credit card or with Paypal funded by a credit card, just to be safe.
The checkbook is held in place by either a plain leather flap or slot.
Thanks!!

I messaged the seller about the colour thing- they replied that the colour in the listing is NOT the same as the one in the photo. That being said... if the photo isn't even of the wallet I would be getting, I'm not too keen to bid on it!
