Wait for more opinions but it does not look genuine. The style number looks like 10337 but the genuine bags with that style number are different and don't have a flap. The one you bought looks like style number 10340, but the stitching on the front and around the creed patch inside the purse is very poor quality compared to a genuine Coach. And the metal hangtag is not the one that came with this style.
I've posted pictures of both genuine styles with those numbers, 10337 on the top and 2 different colors of style 10340 below it along with a photo of a genuine creed patch and the inside of the bag showing how the zipper for the inside pocket is supposed to be sewn - that inside pocket zipper is very badly done on your bag, and that poor quality could NOT have come from a Coach plant. There should also be 2 lines of stitching that go up the center of the flap from the turnlock to the top of the bag.
I believe your bag is counterfeit and another of our experts has said the same.
I think the creed may say #12857, which I think may have only been made for factory.
I'm definitely seeing a zero as the second digit. And did you look at the way the zipper is stitched into the inside pocket? And the 12857s still have the double stitching up the center of the flap and don't have Legacy Stripe lining.

A serial with an 06 year code and single-letter plant code is too early to be in a bag with a style number starting with 12***
