Pokemon Cards
These days children interact on Minecraft or Fortnite and spend their existence online. But it’s not so long since they were collecting Pokemon cards and playing games. Everybody knows Pokemon because it’s one of the biggest franchises in the world. It spawned dozens of video games but the cards were also very popular.

If anybody finds a box of cards in the attic they should scan carefully through them. That’s because some of them fetch hundreds or even thousands of dollars. Collectors take them very seriously and treat them like gold. Meanwhile, some Yu-Gi-Oh and Magic The Gathering cards also have very high values as well (via Sports Illustrated).
