Sky Dancer
Never has a fairy princess made little girls go oooh and aaah more uncontrollably. Sure, some of them were recalled for being dangerous, but that’s what happens when a toy is designed to fly out of your hand like that. This toy had all the drama and momentum a little girl could ever need to fulfill her fairyland fantasies and a little eye-poking sounds like a small price to pay.
Originally sold for about $10, they are worth a lot more now. If you have a set of two dancers (they go by Dazzle and Lacey if you really want to know) you could probably sell it for about 200 dollars.
Atari 2600 'Air Raid'
You keep telling yourself that you've evolved from Atari to Xbox One X and that you're not a kid anymore. Still, we all know you're kidding yourself and there are just too many memories attached to your old Atari games so you keep them in a little box in your linen closet. Would you consider selling those memories if they turn out to be lucrative?
As it turns out, if you dig in that box and find a copy of "Air Raid" you'd be happy to know it could exceed $30,000. It would also be interesting to know that unopened copies with original instruction manuals could be sold for even more.
Pogs
It seems as if the last time we heard the words 'Pogs' and 'Slammers' were at least two decades ago. And that's probably true as they were mostly popular in the '80s. But before you get into a why-am-I-so-old cry, try to think if you have any of the original ones lying around.
In 2016, a six-piece set of holographic Jurassic Park Pogs including a slammer was sold for (you'll need to sit down for this) one million dollars. A full set could still be worth a couple of thousands without a hologram and a slammer.
Polly Pocket
This literally pocket-sized toy could make your pockets happy for a completely different reason. Each of those Polly Pocket sets had different pieces that were incredibly compact but also incredibly easy to lose. On the off-chance you are so incredibly organized and have all the pieces of your old set, this Polly Pocket could buy your lunch for the next two weeks.
Different sets can be sold for different prices (it all depends on how new it is and how many of the original pieces are actually there), but some sets have been sold for 500, 900, and even 1000 dollars.
Webkinz
For those of you who don't know, Webkinz is the slightly more hi-tech version of Beanie Babies. Just like stuffed animals, these look like regular plush toys. These collectible toys, however, come with an online avatar you can play with on the company website.
Webkinz aren't very old, and calling them vintage would be a stretch, but there are some models that have been discontinued. Some of those models are in higher demand than others, but generally speaking, there is a pretty prolific Webkinz market on eBay where you can buy and sell them for about $1,700.
