This is the only graded card on the PSA report. In other words, this is the only graded example of this card in the world. In fact, in the entire set, which has 35 different cards, only 7 have received the PSA 10 grade. Thus, this is an incredibly rare card. Plus, it's a very attractive card. The front is reflective, kind of a chrome appearance.
Among the rarest John Elway cards in existence.
