There are two things that worry me but neither one is strong enough evidence that it's fake.
One is the angle of the brass D-rings for the handle and the long strap. You can see what I mean in the second and thrird photos. Maybe it looks less "off" when it's being carried by one of the straps. Often they'll be on a bit of an angle one way or another but in the photos it looks like a pretty big angle. But at the time, asuming the month & year code are correct, the Willis style was barely a year old so maybe it's just a production mistake.
The other problem is the plant code. The only plant code I've seen "N" used for is Mexico and AFAIK that plant didn't come on line until a few years later. It's possible that there was a short-lived plant that may have used it but so far I haven't seen that code in a confirmed US-made bag. Or again, since this was the first year of the new style serial number that included style and plant codes, maybe someone just made a mistake.
These aren't solid proofs, just things that raise questions, certainly not enough to send it back to the seller as a fake but enough to make me think it might be. I wish it was possible to be more positive either way but I have to say it's "questionable". There are so many new plants opening in the early and mid-1990s and so many new creed stamps being made for each plant that it's impossible to try and document them all.
Smaller problems include the low positioning of the creed and that the little "pillow" bit of extra padding on the leather tab that fits over the turnlock doesn't have as much shape definition at the bottom as it should are causes for concern too. The font and general look of the
Coach logo at the top of the creed seems a bit old for a 1994 bag but again it was a time of major changes and it's hard to find well-documented genuine bags for comparison.
If you're going to keep it, please don't sell it. If the seller will accept returns, I'd suggest sending it back unless it would just cost too much to do that.
