Once you’ve been certified by the Guinness folks as the owner of the world’s largest video game collection, you can either sit around looking at your library… or you can auction it off in the hopes of making a pile of cash.

A Buffalo, NY, man who owns more than 11,000 individual titles (covering 21 different consoles) got the Guinness stamp of world-record-ness back in December. At the time, he estimated its value at somewhere between $700,000 and $800,000 and now he’s testing the market to see if he can get anywhere near that much.

“While I do not wish to part with these games, I have responsibilities that I have made to others and this [auction] is how I will help meet them,” writes the seller in the auction listing on GameGavel.com [via Polygon].

The bidding started last Wednesday at $1, but quickly escalated, jumping from $51,000 to $90,0001 in a single bid on Friday afternoon. As of early Monday morning, the bidding stands at $90,751.

That’s a pretty sizable number, but the listing states that the seller’s reserve price has not been met. There are still several days remaining before the auction closes on Sunday June 15, at 10:30 P.M. ET.

If any of you ends up buying this lot, we hope you’ll be a pal and invite us over for an afternoon of Ninja Golf. We’ll bring the generic ginger ale and rice cakes.
