I collected all sorts of cards for most of my childhood. From Michael Jordan's rookie cards to comic cards, the gulf war set, etc. Used to take a bunch in and trade them to the shop, not really thinking about how the shop owners were taking advantage of a young kid.
I eventually sold a few large boxes, traded them for a PlayStation but kept a small shoe box of the cards I cared about along with a few other large boxes of cards the shop didn't want. I ended up giving those boxes to the nearby thrift store after getting tired of storing and moving them. Kept the small box.
I think that box got stolen from our last move but I didn't realize it until over a year afterwards. The only card I remember now was a 4 player chargers Jersey card that had Drew Brees, Tomlinson, Junior seau, and I think Doug flutie. No idea what that card is worth but I liked it with the Seau Jersey being multi colored (part of the lighting on his shoulder).
Always thought my kids would have liked going through the collection but they have zero interest in sports cards.
