 It is distinguished from the regular set by the refractive quality of the cards.Just like all the other Mantles', cards 15–19 were printed in a 20 percent less quantity than cards 1 through 14.Randomly inserted at the rate of one in 108 series two packs, this 19–card set features redemption cards that made the collector eligible to win the original card whose reprinted design is portrayed on that redemption card front.
