Garbage Pail Kids Cards
Although these trading cards were frowned upon by parents, kids loved this grotesque Cabbage Patch Kids parody. If you find any of these cards laying around, you might be able to earn a tidy sum on eBay, depending on the rarity of the card and its condition. One card recently sold for $300—and an entire 1985 Garbage Pail Kids Series One deck was worth $4,000.
