I've seen another bag with the same creed and serial number that also has both Outlet and impressed rather than just inked Final Sale stamps. The X plant code should also be for the DR, but I'm wondering if this was just a bigger than usual screw-up by Coach. It might be better to just let this one slide. While we've seen one or two fake outlet stamps, I've never seen a fake Final Sale stamp. The creed wording sounds like what they were using in business bags during that time period.
I didn't save the pics of the rest of the bag but here's the other creed
Those creeds were used on the neoprene and mercer bags. I'll look at the years too. Thanks!
