If you were born in the ’90s, chances are you had one of these toys. The Bop It Extreme 2 started off as a stick with three buttons, which later evolved into a five-levered toy. Back in the days, this toy wasn’t worth much, but now you can make good money by selling it online. The Bop It Extreme 2 is reportedly worth $212 if it’s in mint condition with all of its pieces still working.
