For those unfamiliar with why this is listed as a 1/1... It's because these are the base cards from the SP Authentic set. These are considered to be the "true rookies" in the set while others are variants. They are numbered up to the player's jersey number. The final card is the jersey match, and it's the only card that is autographed by the player. So they consider it to be a true rookie 1/1.
