I know it's one of the more rare NES games and this is in amazing condition but this price is seriously insane!! Nintendo World Championship carts don't even go for half that much.

Lucky I still own my original Donkey Kong Jr Math complete in box from back in the day. I actually tried selling it when I was a kid cause it was such a bad game.

but just because they give it that price doesnt mean anyone will buy it, i mean they also have put stuff like twinkies on amazon with a 999.99 price tag

'Stack Up' an even more rare game I believe is only selling for $3,500 complete and sealed. This Donkey Kong Jr Math seller is out of control!! www.ebay.com/itm/Stack-Up-NES-VGA-graded-85-NM-Cardboard-Hangtab-and-Hinge-Sticker-/190881358963?pt=Video_Games_Games&hash=item2c716a6473

Where are these sealed games coming from?

,....

yes i think there are many fake sealed games, they sold a cheap sealed legend of zelda nes games on ebay spain.

I would have bought it if i knew it were real, but i thought they were fake....

Unsold stock from back in the day I guess. Some people probably still have a few lying around. I started collecting NES Black box games 5 or so years ago. The prices were a fraction they are now. I wonder why everyone is all of a sudden raising the prices.

That's his asking price. I highly doubt anyone will offer an amount remotely close to that.

But these 2 games have been graded by the Video Game Authority

I've never seen an asking price as ridiculous as that though. The seller is out of control
