Your vintage video game systems, old iPods and disco-era TVs could be worth big bucks

Older video game systems are hot on the resale market as collectors seek items no longer in production. Are you sitting on a forgotten-gadget goldmine? Dusty video game systems, old TVs and record players, and abandoned iPods often seem like trash. "Vintage electronics are hot sellers," says Jordan Barnes, senior director for resale app Mercari. For instance, over the past 90 days, interest in the original Nintendo's GameBoy, Gameboy Advance and Gameboy Micro game players have surged to more than 200,000 searches, with sale prices topping $90, he says.
