I dunno where to put this but i guess this is related to NES. According to
What treasures are in your attic?
Everyday folk discovering colossally valuable collectors' items amid
everyday junk has been the lifeblood of antiques shows for years, but it's not every day you see a real-life gold-in-the-attic tale play out on eBay.
Last week, North Carolina eBay user lace_thongs35 thought she was putting up an everyday, 80s-era Nintendo Entertainment System (together with five games) up on the popular auction site. But less than an hour after the first bid, the price was over $6,000 -- and on Wednesday, when the auction closed, the final selling price topped $13,000.
Why? Not the console itself, but one of the games bundled with it -- a deeply obscure 1987 release called Stadium Events, a highly sought-after collectors' item. But it wasn't even the game itself that was worth the bulk of the money -- it was the original cardboard box, which collectors value at a breathtaking $10,000. Fewer than 10 complete copies of the game are thought to exist, and retro gaming aficionados consider it one of the hardest-to-find NES games ever made.
Bet you're wishing you hadn't let Mom throw out your Nintendo collection now, eh?
