This is one of the more intriguing Atari collectibles. Coca-Cola asked Atari to create a game for their employees in Atlanta. For this, Atari modified Space Invaders so that players shoot the letters "P E P S I" instead of alien invaders. Only 125 copies of the game were produced. It doesn’t come in a real box, just a weak Styrofoam case. So it's not technically a prototype, but it also wasn’t sold to the public. And no, Coca-Cola doesn’t have any copies remaining.
