Official Super Nintendo Seals:
All official SNES seals should include a horizontal seam on the top & bottom (the length of the box) + a vertical seal on the back of the box that intersects with the 2 horizontal seams. Another factor is the intersection of the seal should have a fold in the plastic. A few other factors are relevant such as a vent hole or type of plastic used.
