Game Boy – $1K

Back when far-advanced gadgets like tablets and smartphones came barging into adult lives, most kids were killing time with this bad boy. This handheld console made by Nintendo was first released in Japan in 1989 before making its way to North America in the same year.

It underwent many development stages and Nintendo had released several versions, many of which were a hit among the gaming consumers. In 1998, the company launched the Game Boy Light, which has an electroluminescent backlight for playing in dark rooms. On eBay, this could sell for $1K.
