How much is someone willing to pay online for a '85 Nintendo that works?

I will also sell it with all of the wires that comes with it, 3 different controlers (1 regular one, 1 joystick one, and 1 gun {for the duck shooting game}), a storage case that holds 11 games, and 16 games (one of them being the original Super Mario Bros). Did I mention that it works?|||With the release of the Virtual Console, the value of the NES/Famicon may go down. Still, it is like an artifact, so you still may be able to sell it at a good price.|||I'll pay $8.50 cash, plus shipping.
