I was just thinking about a deal I made a while back, and it stemmed from what many parents/grandparents did back in the 80s/90s. They bought their child/grandchild baseball cards in hopes of paying for their college tuition. It was seen as a solid investment, thanks to the skyrocketing interest and prices in baseball cards from that time period.
Well, I ran into such a person - it was a college kid who realized his topps sets he was given (one a year from 1983 to 2006, I believe) wasn't quite going to pay his way through Harvard, so he wanted to unload them.
And unload them, he did. He sold them for what a few college books from your local community college would go for. That is a far cry from putting you through college. Could you imagine? That was the mentality back then though. What a bummer to realize the true value of cards are a mere fraction of what you thought they would be worth!
It was fun to have that run of Topps sets. I didn't hang onto them for long, as I had purchased a large collection the day before, for about $1,000 that had many jersey/autographed cards and then sold everything as a lot for $2,000 to someone else. I was able to keep some pretty cool stuff too, which is always nice!
