Some toys, gadgets, and pop culture items we grew up with are worth much more than anyone expected. You could be sitting on something valuable right now without even knowing it.
If you've got any of these tucked away in a closet or attic, it might be time to take a second look.

You might’ve battled friends with them at lunch, but those same shiny cards could buy you a house today. A first-edition Charizard in pristine condition has sold for over $250,000. Even lesser-known cards from the authentic 1999 set fetch hundreds, especially if they’re graded by PSA.

Long before mobile apps and Fortnite, the Game Boy ruled recess. It changed how people played on the go, and fans know it. A working, boxed model in clean condition can be worth more than $1,000. Rarer editions, like the Tommy Hilfiger collab, sell for even more.

If you somehow still own the UK edition of Harry Potter and the Philosopher’s Stone from 1997, you’re sitting on a treasure. Only 500 were printed for libraries. One recently sold for over $100,000. Look for the print line and typos—they’re what auctioneers crave most.

That plastic Luke Skywalker from your childhood, especially from the Kenner line, might be worth more than your current phone. Figures like a rocket-firing Boba Fett or a vinyl-cape Jawa can sell for $10,000 and up, especially if they’re still in unopened packages.

Character-themed PEZ from the ’50s and ’60s, like the “Space Gun” or early Mickey Mouse, can command serious prices at auction. The weirder or rarer, the better. Believe it or not, these PEZ dispensers were never just candy holders. They were low-key collectible art.

Apple’s first products became cultural artifacts even though they were just tech. These gadgets represent the dawn of the digital age, and serious collectors will pay for that legacy. An original Apple I has sold for over $500,000. Even first-generation iPods, if they’re sealed, can go for hundreds.

Redline Hot Wheels were mini muscle cars made from 1968 to 1977. They’ve become incredibly collectible. The most sought-after model, the 1969 Pink Beach Bomb, once sold for over $150,000. Wheels with red stripes and rare colors drive prices higher.

Before Marvel became a movie empire, its comics told the origin stories. If you have Amazing Fantasy #15, which introduced Spider-Man, you’re holding serious value. One pristine copy went for $3.6 million. First appearances and high-grade condition are what enthusiasts chase the hardest.

Barbie’s first appearance in 1959 was in a striped swimsuit and high heels, and she’s been cashing in ever since. A first-edition Barbie with the “Japan” stamp on her foot can sell for over $25,000. Her mint condition, original box, and accessories make her even more desirable.

Sports trading cards were once kept in shoeboxes. Now they’re six-figure investments. Michael Jordan’s 1986 Fleer rookie card sold for $738,000. Graded cards from the ’90s, especially of legends like Kobe Bryant or Ken Griffey Jr., have also surged in value, particularly if they’ve been kept in near-perfect shape.

Remember constantly checking your digital pet to keep it alive? That little keychain could now net you some real cash.

Before everything went digital, games came in cartridges. And now, those cartridges come with big price tags. A sealed copy of Stadium Events for NES has sold for more than $40,000. Games with low print runs or factory-sealed boxes have become trophies for serious buyers.

Vinyl survived and eventually became elite. Original pressings of albums by The Beatles, Led Zeppelin, or Nirvana have fetched impressive sums. Clean conditions, rare label errors, and unique packaging are most valued.

That chair your grandparents never threw out might be worth more than your living room set. Original mid-century furniture, especially by Eames, Knoll, or Saarinen, has hefty price tags. Authenticity, condition, and designer name matter most.
