Man I would still play with baseball cards all the time if you could still buy them a couple packs for a dollar. I had a huge collection at one time. My folks would buy us each a box every year for our stocking from 1979 til about 1985, and we'd spend every spare penny on cards on our own.
I still have a notebook with all of my George Brett cards and all of my good rookie cards that didnt get wrecked during trading and endless sorting and comparing. They were worth a fair amount at one time, in fact I think the highest value I ever saw was about $1500 for my Cal Ripken rookie. I do have multiple rookies (different brands) of a lot of great players who started in the 80s.
We had a fair amount of 68-69 cards that my dad had held onto. My brother snagged those but I was never bothered. He has some good guys but no nothing real valuable from those years.
