Now come on. First of all by the eBay tag name I qwill assume this is someone who "collects" Nintendo. I will go out on a limb and guess that they know that NES protos are highly sought after.
Now if you were a NES collector and you came across one of these in your travels what is the FIRST thing you would do after you got it home.
You would plug it in.
Yet the seller doesn't mention if it works or not. Which game it is or if it differs from a released version. I guess we should all assume its Airball and start the bidding at $900.00
He just happend to come across a NES cart with no label and first thing he did was post it on ebay. If you thought for one second that you had a proto you would show that it was indeed a proto so that you could get market value. Only a person who pretty much assumes it isn't a proto would post in this manner.
