25 Highly Valuable Games You Might Actually Own

22. Donkey Kong Country 3

Platform: SNES Released: 1996 Potential Sealed Price: $1,500 Potential Used/Worn Price: $300 While not quite as celebrated as some other entries in the series, Donkey Kong Country 3 is still renowned as among Nintendo's greatest platformers. It has since had renewed interest with its popularity on the Wii Virtual Console.

It's also a popular item among collectors, with sealed copies of the game selling for just under $1,500. Good quality boxed versions are also worth a pretty penny, regularly selling in excess of $200.

21. Final Fantasy X

Platform: Playstation 2 Released: 2001 Potential Sealed Price: $400 Potential Used/Worn Price: $10

One of the most popular RPGs for the Playstation 2, Final Fantasy X introduced a whole new generation to Square's beloved series. The graphics have stood the test of time well, and the game featured a host of memorable characters. The HD remaster of Final Fantasy X for the Vita and PS3 hurt prices of unsealed copies substantially, with used products going for under $10.

However, if you've got a sealed copy (with the original black label) lying around, then you'll be happy to know that they're going for at least $300 on eBay right now.
