I thought I’d quickly mention this Atari Club Video Game Masters Gravitar Patch. This iron on patch was created to serve as a prize for the Atari Club Video Game Masters Competition in 1983-84. Three games were included in the contest which were Gravitar, Quadrun, and Battlezone. These patches were never sold to any stores and never given out to the public, so they are certainly rare.
Seller also mentions:
“You are bidding on an Ultra Rare Vintage Atari Club Video Game Masters – Gravitar Iron On Patch. Patch was only available from the Atari Club and handed out to the competitors who scored more then the 15,000 point mark in the game. I do not know how many were handed out or how many were made. I do remember that I scored the max that could be achieved on the game and so did about 10 others.“
