6. Superballs - Estimated Value $30
Did you ever beg your parents for a dollar to buy Superballs? If so, you weren’t alone—millions of kids and adults were captivated by these high-bouncing rubber balls. While they seemed simple, their ability to bounce incredibly high made them a sensation. And they’re still popular today.
Invented by scientist Norman Stingley in 1964, Superballs quickly became a cultural phenomenon. Made from a synthetic rubber compound called Zectron, these small, unassuming balls had an extraordinary bounce. Kids and adults alike were amazed by how high they could soar when thrown with enough force. By 1965, over 6 million Superballs had been sold, and they even made their way into pop culture, inspiring songs and appearing on TV shows.
While you might have paid $1 for a pack of Superballs in the 1960s, today they can be worth around $30. Not a huge profit, but still a nice return! Vintage Superballs in their original packaging or from limited-edition runs can fetch even more. Early versions, which were slightly larger and came in a wider range of colors than later releases, are particularly sought after by collectors. Nostalgia plays a big role in their current value, as many adults fondly remember the simple joy of bouncing these balls to seemingly impossible heights.
