American Girl Molly
Molly McIntire, one of the American Girl doll series, grew up during World War II and moved to America. This doll has such a life story it might as well be somebody’s grandmother. Molly dolls first found their way into American toy stores in 1986, and they were discontinued in 2013 only to make a comeback in 2018.
An original Molly from 1986 is considered a collector’s edition, and one of those was sold for $1,200 in 2018. Molly dolls from different years can still be worth more than their original value, but not as much as their 1986 sisters. Other dolls from the series, such as Kanani Akina or Samantha Parkington are also valuable.
Nintendo's 'Stadium Events'
Toy collectors and vintage gamers make up the buyer's market for original cartridges of Nintendo games, and they will pay even more if the box has never been opened. Nintendo's 'Stadium Events' was released in 1987, but it only took a year for the name and the game to be changed.
This is exactly what makes this game so rare. In 2017, which wasn't that long ago, an original game in an original sealed box was bought for the absurd price of nearly $42,000. Suddenly, looking through the boxes of old toys in your mom's basement is starting to sound like the best idea you've ever had.
Vintage Lego Sets
The Lego factory was first founded in Denmark in 1932 and it has been making those little bricks ever since. This means that getting a standard Lego set is not that big of a deal. However, not all Lego sets are still being manufactured. If you find such a set that has never been opened and has all of its pieces, you could be looking at your next month's rent.
In 2015, for example, a limited edition of the Lego H.C. Anderson's Clumsy Hans was handed out to about 80 Lego executives. Get your hands on one of those and you could sell it for $2,000! So next time you step barefoot on one of those little blocks of plastic and wish you were never born, try to remember that this could in fact be your lucky day.
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.
