Is anyone else shocked that 80s baseball cards are almost worthless?

[Matt24]

I have over 300 boxes unopened, all from 87-92, mostly baseball. Have 20 boxes of 87 fleer which had a ton of good rookies. Got 40 Hoops 91 or something, they are worth like 5 a piece, ha. I have a ton of cards that I want to get graded including the whole bball 86 fleer but havent done it. Have a bunch of Upper Deck boxes with Jr's rookie too, but I know those have gone down a ton. Ah well. If my poker run keeps going, I'm going to have to sell all them to build back my bankroll.

Fav Set: 81 topps bball I believe. Bird/Magic/Erving on one card. Dad bought a few sets of those for me and my brother for next to nothing.
