There's a great Netflix Documentary called Jack of All trades. It's about a kid who's mother told him he had to move his old cards out of her condo, and as he's going through them it brings up all these memories of childhood. He also goes to see what they are worth only to realize most 90s cards are worthless. It even touches on how Upper Deck were a bunch of shadeballs making thousands of sheets of valuable cards devaluing them and kind of defrauding their customers. Decent watch
