Nintendo 64 Games

Nintendo 64 games will get you a sizable return on investment — at least $750 today from the original average price of $60. It’s worth noting that getting that $750 price tag is only possible if you have the right game. One of the most prized game cartridges is the Mario Kart 64, and it’d have to be in mint condition as well as in an unopened box for you to be able to sell it for that price.

Another prized game cartridge is Harvest Moon, and it’s a rare one that’ll fetch at least $900. And, no, Harvest Moon isn’t a Neil Young game, but it’s an iconic farming game that was never mass-produced. People weren’t playing farm games back then, and apparently, its loyal fanbase inflated its value to what it is today!
