We are living in the junk wax era right now and no one knows it yet. What is driving modern demand? People seeing vintage go up in value over 20 years. People think that is repeatable with modern. But it’s not - everyone is a closet full of modern investor and everything is kept pristine. Vintage is valuable because it was played with and thrown out by our moms (or for me, my aunt). Pokemon is overprinting right now to keep up with this “demand” to fill the closets.
The same thing happened with baseball. 50s and 60s cards are worth a lot. People started realizing this in the 80s and started hoarding. But they are worth a lot because the cards went into bicycle spokes. Baseball cards were overprinted in the 80s and 90s, creating their junk wax era.
