I used to collect cards in the late 60s and early 70s. Sold them as a junior in high school for about $20 and thought I’d made out like a bandit. Somehow, a few strays showed up in an attic after a couple of moves. One was a Topps 1973 Roberto Clemente (issued before his death but had his final career stats -3,000 hits - on the back). I have no idea what it is worth today but I can’t imagine it’s worth more than $50.
I have several unopened Topps complete season boxes and have thought about selling those many times, then I think if I break open the box and get the Ken Griffey Jr. rookie card, I could make out like a banshee.
I also bought into the Javey Lopez rookie card sensation and lost a couple of shirts.
I do it know for the kids and hope that they will enjoy the cards and remember what life and baseball was like back then.
