It's hard to say for sure, that J8P- prefix has usually been used in bags made at the Costa Rica plant, and it would be unusual for bags using the same plant code and made in the same month and year to come from 2 different locations. It's possible but without more evidence I can't be 100 percent sure. So possibly genuine with a question mark.
Also the brighter blue thread showing in several of the photos is ringing alarm bells - the stitching in those areas should match the leather exactly.
Coach had plenty of experience in getting thread to match their leathers and an obvious color difference worries me unless large parts of that bag have been restitched by someone who couldn't find thread to match. The stitching in the photo of the leather tab holding the D-ring for the strap doesn't look even either, I'm seeing different-size stitches.
