The Guinness-approved record holder for the largest video game collection in the world has decided for a trade-in.

Polygon reports that Michael Thomasson has decided to sell his gargantuan haul of video games and consoles that he has been collecting for decades. This collection was declared to be the largest in the world by Guinness World Records when they counted 10,607 games at Michael's residence back in December. Thomasson claims he has purchased over 400 more titles since then, pushing the overall number of owned titles to 11,000+. How did Thomasson accumulate such a massive library? He operated seven gaming stories throughout the 1990s and early 2000s and has worked at a retail gaming chain for the past decade.

You can follow the bidding on this mother lode of gaming history at GameGavel. Michael Thomasson claims his collection is valued somewhere between $700,000 and $800,000. The auction's undisclosed reserve price has not yet been met, but bidding has currently reached $98,500. Bidding ends one week from today on June 15.

Thomasson claims he has not given up on gaming -- he actually teaches college courses on the subject. He is selling his collection for the sake of helping out his family. The collector mentioned he sold his entire library twice in the past and was able to rebuild his collection both times.
