How can I tell if a vintage Gucci bag is real?

An authentic Gucci bag often has a serial number stitched on a tag in the bag's interior. Gucci serial numbers don't contain letters, and any letters present in the serial number are an indication that your bag is a fake. Check the bag for any signs of messy craftsmanship — luxury goods have impeccable stitching and stray threads are a warning sign. Ensure the hardware is of good quality and not rusted or chipped.
