That happened to me years ago. well, not the 15 cents, and it was one of those holographic cards.
This was back when we thought they would actually be worth more money. haha, what dumbasses we were. It was a Dark Porygon 2 card if I recall. I still have all my old cards. No idea why. they are worth something, but I doubt their value will be going up anytime soon.
But hey, it's usually the stuff nobody thinks will be worth anything and that get's thrown away by everybody that becomes rare and collectable- because everybody threw them away...
As for expensive tech stuff, I actually don't think I ever had anything stolen. Warranted, when I was in school all I had that could have been stolen would have been a old 8 year old laptop and a slow, ancient USB flash drive.
