Is Allison's Old Pokemon Card Collection Worth Anything?

Do you have anything laying around the house that you're certain will be valuable one day? I had a bunch of baseball cards from 1966 that my mom's friend gave me that her son left at her house when he moved away. I kept them for years and they only were worth a little bit.

Allison's Pokemon collection is now Carson's. We looked up some online and it seems they might be worth something but not much.

What is in your house that you're waiting to be valuable? Comment below!
