I'm curious what would be the value - or rather how one can put the value on the prototype console. Before launching the companies would make several prototype consoles to iron out any issue - from very early hardware testing model down to the very early pre-production models to work out the bugs..

I'm wondering how one would put the value on one of these? Since these were never meant to be sent outside the company lab I know it's very hard to come by but you do come across when you are at the right place and right time.

Case in point. Sega made handful of Saturn consoles using some of their dev machine motherboards to show around the trade show before Saturn's official launch. Those machines were belong to Sega Japan and upon official release of Saturn in Japan would have been locked up away except one or two from my understanding somehow escaped. Now how much would you put the value on one of these machine? Any guess? ^ ^
