Quoted from goatdan:

I heard that the Striker number was much higher. That may be what stayed domestically, but it seemed from my small sample size it did decent domestically too. I know there were three in route in Milwaukee at once at one point.
Dale Jr was technically a Limited Edition of Nascar so it shouldn't necessarily be in this list. It sold very slowly because it came out after Nascar which wasn't overly well received and was very specific about one racer, so you were taking the Nascar audience and then splintering them further.
As others have mentioned, rarity rarely equals value. My belief is that unlike, say, video game collecting, since pins are so big we are all limited by how much we can fit. I don't want a rare game that is horrible taking up space I could use for something that I want to play!
I have a Viza War. As far as I know, there are two working ones period. It is not a great game. If I was to sell it, I think I would be lucky to get a few hundred for it. Luckily, it makes a nice end Table, so I keep it basically just for that!

Those gold and platinum ones I hate seeing on lists. I liked it when pinball machines were made with one version. It’s a monopoly and it’s an Austin powers as far as I am concerned.
