Ball cards ....
My father was one of many in his generation that took many a Mickey Mantle ball card (among many others) and ran them through bicycle spokes or stuck them on a fence and shot them. He bought ball cards just for the gum and did who know what all with the cards. The gum now - that was valuable to those kids. These are not vague memories for people in that generation.
Now, back in the late 70's-80's, people from my father's generation found themselves with 10 year-old sons on their hands. And what did they do with/for those 10-year old boys? Why, they invested and bought ball cards! It's fun. And look what those Mickey Mantle cards are worth now? Maybe this Dan Marino card will be worth more in 10 years. Maybe this Michael Jordan card with feed my grandkids.
If my dad could have only found that one shoebox of cards that he had stashed away somewhere in his mother's house. He looked many times for it. But he swears that granny threw it out. Just threw it out.
Now, it turns out that almost every single penny that my father (and my brother and I) spent on ball cards is about the same. We were just throwing the money out. I got my ball cards out a couple years ago. Several boxes "worth." And that's about all they were worth was the space they were taking up. I sorted a bit, and I came up with some of the more collectible cards. I sold those for $40. The rest (read several thousands) I sold to some dupe in my office for $10.
If only I could have gotten the gum back at least from some of those Topps baseball packs. Now, that gum would have been worth it.
