While at a thrift store in California a very rare prototype Atari console was discovered. It was purchased for $30, later sold for $3,000!

The discovery was an Atari 2700, the supposed follow-up to the 2600. The 2700 really isn’t any different from the 2600, the biggest difference between them is a pair of wireless controllers (as opposed to wired ones) and the overall physical appearance.

While It is unclear how many of these systems exist, former Atari employee Dan Kramer has stated that at least 12 consoles were made, plus extra controllers.
