Trading card expert Roy Raftery looked through our cards to see whether our childhood collections had grown in value since buying them nearly 20 years ago.
Popular cards seen in the show had the most value, such as the famous Dark Magician, Mirror Force and Blue Eyes White Dragon. Original prints of powerful, banned cards also fetch a high price too.
The notorious Chaos Emperor Dragon – Envoy of the End, a trading card that has been banned since 2004, can sell for up to $100.
Do we possess any other cards that go over the $100 mark? Watch the video and find out!
