[quote name='pimp tyranny']i'm wondering when or if someone's made a duplicate and sold it. doesn't seem too hard, get a cheapass NES game, take the label off, create your own label, cut a square out of the plastic casing, craft a little switchy think, and voila, 5000 dollars.
you could even get a gold LoZ cart and sell it for 10000.[/QUOTE]
You'd never get it to look exactly like the real ones, and you'd be called out on it. The board inside was only for this cart and prototypes. Most NES boards only take up 25% of the inside, if that. Even if you could recreate the timer switches, you'd still be left with no proper board in the background.
This auction will not go through. The $5000 is due to a zero feedback bidder who will not follow through and pay. These realistically go for $1500-$2000. Golds have gone for anywhere from $2500 to $7000.
I have a grey one (#215) of my own as well... traded 4 hard as shit PAL games for it. Well worth it, considering I only spent about $500 total on those carts. The numbers go up to 343, but there are approx. 120 of them, for sure, in non-NOA hands.
Quackzilla, that's a pretty big claim to make, a few more details about your cart?
