2013 Panini Prizm Silver #33 Giannis Antetokounmpo Rookie Autograph 5/25 - Pop 1 Only Example in the World! PSA GEM MINT 10 - Auto 10. As unique as its subject, this one-of-a-kind card is as likely to skyrocket in value as much as the talent of the Greek Goliath. Incredibly promising 2013 Prizm Silver rookie autograph of Antetokounmpo is one of the top five Giannis cards ever auctioned publicly; numbered 5/25 and only five have been graded by PSA. There are only three PSA 10s of this card in existence and this is THE ONLY one with a perfect 10 graded autograph. One of the other 10s has an incredibly faded signature, and the final of the trio is tucked away. Described on the back caption, "With the ball-handling and court vision of a point guard and the body of an athletic power forward, Antetokounmpo has the ability to play just about any position on the court. He has already earned MVP honors in each of his past two seasons and as this phenom enters his prime his value is almost sure to explode - along with the value of this card. Perfect rookie auto signed in 2013.
