1998 Upper Deck Retro is the company's first nostalgia-based card set. Packs were sold in six different collectible lunchboxes, 24 packs per box. All cards are printed on super-thick card stock stock card and has a distinct "retro" feel. The Quantum Leap parallel is numbered to 50, and often hard to find in hard grade due to its unique die cut. Beckett has only graded 5 total examples of this issue. The Jeter example here for auction is a POP 3, with none graded higher.
