At the 2000 Bell Canadian Open, Tiger Woods hit what many consider the greatest shot of his entire illustrious career. It was a 218 yard shot in the rain from the fairway bunker on the 18th hole on Sunday. Scott Verplank called it "the greatest shot I've ever seen in my life." After Tiger's victory - his 24th PGA Tour win of his young career, his own caddie Steve Williams walked back to that spot from the 18th hole fairway bunker just to marvel at what had happened. 

It was a legendary moment. Tiger hit the shot of his career, and he notched his 24th PGA Tour victory in the process. So how many tickets still exist from this rainy Sunday in Canada in 2000? PSA has only graded 4. That's right, only 4.
