Growing up in the '00s was a blissful time. Most of our thoughts were consumed by the Olsen twins (opens in new tab)' love life, how much black eyeliner was too much black eyeliner, and whether or not our jean skirt (opens in new tab) was short enough. If you kept a lot of your favorite memories from that era to remind yourself of how great it was, we don't blame you. Even better news? All of that stuff hidden under your bed—I'm talking Beanie Babies, Furbies, and even your old faithful T-Mobile Sidekick—is about to bring you some serious cash. So, before your mother threatens to take it all to Goodwill for the hundredth time, take a look through today's 40 most sought-out '00s items, ahead.
'Lizzie McGuire' Cookie Jar
An iconic Lizzie McGuire cookie jar (opens in new tab)would be worth around $150 today. Personally, I'm ready to drop some cash to spice up my kitchen decor.

Arguably the world's best arcade game, this special edition of Dance Dance Revolution is worth $250 (opens in new tab), and that's without including the legendary GameCube console.
Polly Pocket Playsets
If somehow you attempted to go your whole childhood without losing Polly Pocket pieces, then you deserve a medal. This Rollercoaster Resort (all pieces included) (opens in new tab) now runs for $340, so I guess it does pay off to be organized as a kid?

Hot Wheels Highway 35 World Race Ultimate Track Set
Only 1,000 of these bad boys were ever made, so if you have your hands on one, consider yourself lucky. Since they're so rare, they can sell (opens in new tab) for up to $4,500. (Yes, you read that correctly.)
Mary-Kate and Ashley Dolls
Was it a '00s sleepover if a movie from the dynamic twin duo didn't make an appearance during the night? While the twins' films are easier to come by, their dolls are not. These two, pictured here, are worth a very normal price of $308. (opens in new tab)
Marie Antoinette Barbie
This limited-edition Marie Antoinette doll is extravagant, and I wouldn't have it any other way. Her shoes aren't plastic but porcelain for crying out loud! The one-of-a-kind doll is worth some serious dough (opens in new tab), ringing in at $1,100.
Wii Disney Sing It Family Hits Nintendo Wii Game
Karaoke but make it at-home. This game came in a variety of versions, from Disney Channel hits to Glee favorites. It's not worth as much (opens in new tab) as others on this list, but $70 is still some serious money!
T-Mobile Sidekick
Before iPhone's were all the rage, you very desperately wanted a sidekick. The way it kick-flipped it's way up to reveal the keyboard was the textbook definition of a chef's kiss. If you're feeling like trading in your iPhone for one of these (opens in new tab), it's going to ring you up to $280.
Monopoly: Simpsons Treehouse Of Horror
Based on the famous Simpson episode of the same name, this favorite board game gets a creepy cartoon spin featuring six glow-in-the-dark pieces! Maybe that's why it's worth (opens in new tab) $300?

Apple iPod Nano
The life-changing music device doesn't go for much as you would think. But if you never opened yours from the package (who hurt you?!), a nice $1,000 (opens in new tab) could be coming to your bank account in the future.
Blockbuster Card
