Back in the early 90's when there weren't alot of prototypes out there and they could be had fairly cheaply if you knew where to look, they could have been in investment (although no one ever really thought of them that way). Nowdays there are tons of them floating around out there and the price has fallen alot. A proto that would have gone for $150 just 5 years ago goes for about $70 today. Personally I only collect prototypes so I can examine and review them, not for investment. If you're looking to invest in something classic gaming related, try boxed 2600 games. Those can still be found relatively cheaply and seem to be going up in value.
But then again if you're just interested in buying this stuff for an investment, you're in the wrong hobby...

Tempest are the majority of these prototypes copies or are they originals and if they are original where did they all suddenly come from? On that question how many prototypes did a game on average possess before it was finally released? I ask for on your site you list two or three different versions of the same prototype

All of my prototypes are originals, and most of the ones I reviewed were originals. Usually the only time I used copies were when I was reviewing prototypes found on the 5200 Multicart.
I have no idea how many copies of each prototype were made. I guess it all depends on how big the company was, how far the game got into development, how long it took them to debug it, etc. As for where did all the prototypes come from? I think you'll find that lots of people kept their review copies or took several prototypes with them when they left their company. Now that classic gaming is in style, people are digging through attics looking for that old box of prototypes they have.
