There's a BIG problem with the serial number. The Tribeca line wasn't introduced until early 1998, and first appears in the "New Collections" catalog from that time. This is backed up by other bags with style numbers starting with 90xx with the last two numbers toward the high end of that sequence. There may be a rare number like 9085 that goes back a lot farther but Coach usually followed a definite pattern in the number sequence and a bag supposedly made in late 1995 just doesn't fit. The font of the serial number is also totally wrong for a bag from the C plant made in 1995.
There are other problems too including the stitching and the stamp on the front but the serial number is what's raising a big red flag. The color seems odd too, it should be a dark muted olive green closer to what's shown in the hangtag photo but the photos of the inside look as if the natural suede inside is almost a light gray. I know you can never depend on the colors shown in photos but this seems pretty extreme. There's a genuine one here for comparison:

I don't recommend buying that bag.
