I collected baseball cards when I was a kid.
For Christmas Granny and Papa often bought me a complete set of Topps or Upper Deck or Fleer cards. I knew before unwrapping it what the present was because of its oblong shape. (It was either that or a decanter of liquor.)
Being the weirdo that I am, I never opened the boxes. I knew they had more value in mint condition than if I got them out and played with them.

So rather than mess them up, I bought a Beckett pricing guide so I could see how much individual cards in those boxes were worth.
One year I received a Topps 1992 complete box set. Checking the guide, I noticed a card from a couple of years before with a ridiculously high price tag and an exclamation mark after it.
