Nintendo Game Boy ($4,000)
When I was a kid, everyone wanted a Game Boy. Released in 1989, these handheld gaming systems actually hung around until the early 2000s. Fast forward to today, and now it looks like everyone wants a Game Boy again! They can be worth hundreds to thousands of dollars, and a new, unopened Game Boy reportedly sold for $4,000 on eBay.
Admittedly, the reason most people might want a Game Boy is because of their worth alone, and not necessarily to play considering the many hand-held options available these days.
