How much is an Atari 2600 worth?

I am trying to collect old retro consoles so far I got a Nes,Sega genesis,an if it counts N64. I want an atari 2600 an I think a guy near me sells em for $15Doctalen

As much as someone is willing to pay for it.

i would personally pay $30 tops. as with anything, its worth what you're willing to pay for it.

You can get them ebaysably (tell me somone else gets that) from about $35-$100 depending on the models, which someone handsomly put in picture form for you above.

I bought the Atari 2600 Jr. with all the hook-ups, two joysticks, the twin paddle controllers, a 9-digit pad controller, and like 30 games. And that cost me $50 all together, plus the guy threw in an official Atari Video Game Organizer with it. I hate the stupid rainbow thing on it, but other than that it's not a bad looking system.
