I agree. The grommets are a problem, and the font used in the serial number is an even bigger problem. The oversized "o" in "No" just by itself would be a big red flag. A similar font rarely shows up in genuine bags but it shows up a LOT in fakes.
Another problem I'm seeing is the inside zipper and the edges of the leather it's attached to. The leather edges at both the top and bottom of the zipper should be rolled and tucked & sewn under the zipper. On this one the edges especially the lower one seem to be unfinished and unrolled. The stitches around the inside pocket zipper also seem to be twice as long as they are in genuine Pat's Legacy bags. Each stitch should only be about the distance of one zipper tooth and the gap on one side to the next one, instead they are twice that length. And in the picture of the back of the buckle assembly the rivet is too big and the length between the rivet and the rest of the buckle is too short.
We'd definitely want to see photos of the full pocket zipper all the way to and past the edges of the inside pocket and the backs of the strap buckles.
As to what the seller says in their listings, that's all well and good but then it becomes the buyer's responsibility to prove that the bag is fake. And if the seller has a so-called "authentication" from an authenticating service that's incompetant to analyze Coach products (this one doesn't but it can and will happen and probably already has) the problem gets much harder. That seller has listed fakes before, knowingly or otherwise.
Top 2 pics - genuine on top ( leather top zipper pull), probable fake below.
3rd & 4th pics - length of the stitches and how the leather around the inside pocket is sewn (doesn't show clearly on the pic but I've verified it AND the difference in the length of the stitches in my own genuine Pat's Legacy M5D-9951 from the D plant in Dec 1995. Number 3 is genuine, Number 4 is probably fake
