Looking back, it’s funny how things change. As kids, we were obsessed with getting the latest toys from our favorite TV shows and characters, eager to show them off and share with friends.

Eventually, we outgrew them and tucked them away for years.

If only we had known how valuable they’d become! Time to start digging through those boxes—you never know what treasures you might find!

Mego Elastic Batman ($1500)

For starters, there’s always a new Batman reboot, which means another wave of popular action figures. But take a look at this rare gem—the Mego Elastic Batman, released in 1980, with only two ever made.

Designed as an alternative to the standard 8″ figure, which was losing popularity by the late ’70s, the Elastic Batman never made it to full production.

When prototypes were created, toy company Kenner sued Mego, claiming the design was too similar to their Stretch Armstrong toy.

The lawsuit shut down the product, leaving just two in existence—one of which sold for $15,000 in 2006.
