Sports card collecting

In the past I've wondered if cards will ever make a comeback? I'm betting they will at some point.....probably generations from now. The problem with cards is how saturated the market got in the late 80's and early 90's. That's what started the downfall IMO. I have a couple of binders stored somewhere that the kids will end up with when I'm dead and gone. Hopefully someone gets some money out of it someday.
I have probably 5000 football cards from this era that will likely remain worthless.
