Set
1989 Upper Deck
3 cards in the JW50
The startup set that changed the industry.
Debut set of a startup that nobody trusted. Tamper-proof packs, hologram-backed cards, whiter stock, and a #1 card of a 19-year-old outfielder scouts had already inevitabilized. When Griffey started producing, the price of the set went vertical and Upper Deck went from wax-shop skepticism to industry disruptor in eighteen months. Every innovation you associate with 'premium' cards traces back here.
