Well, for starters each card is jam-packed with a top quality action photograph and a facsimile autograph. As if that wasnt enough, there are also randomly inserted short-printed rookie cards and certified rookie autographs, as well.
Some of the top-flight rookie cards you may find include Jose Capellan and Kaz Matsui, just to name a few.
And what would a set be without its share of parallels. Pro Sigs boasts 4 tiers of them, in fact, including a Blue parallel serial-numbered to 25 and a Red parallel serial-numbered to just 10 copies!
As for guarantees, every box promises at least one autograph on average.
A 24-pack hobby box of Pro Sigs retails for $49.95.
