re: Will baseball cards from the 80’s-90’s ever be worth anything?

I was a huge collector of basketball and Marvel cards in the late 80s and early 90s when I was a kid. Spent tons of money completing the 1992 Marvel Masterpiece series. It was an "investment" and at the time, a full set went for $500.

Now you can buy an entire set and all the special cards for $20. Still, I love them and still have them to this day. Pure nostalgia.
