If you lived through the '90s, you probably have a cache of Ty Beanie Babies somewhere in your home (unless you've already cashed in on the plush toys). According to an eBay buying guide, some of the most profitable plushes include Peanut the Royal Blue Elephant ($1,500-$5,000), the Victorian-style Old Face Teddy Bear ($2,000), and Chef Robuchon ($7,353.51), a bear dressed like the Michelin-starred French chef Joël Robuchon.
That said, most Beanie Babies aren't actually worth much.
