My Mom Said She Found My Garbage Kid Cards

After being lost for years, the old Garbage Kid Card collection from my youth was recovered. I have no idea why I collected these as a young person, but now is a perfect time to trade them off to turn into something useful.

My children ask me "What do you do with these." I had no answer. "Uhh, collect them." Then I thought some more "They're stickers!"

I put a bunch in plastic sleeves, I wonder if I have anything valuable in here?
