I found two sets of three Channel F games - Videocart 1: Tic-Tac-Toe, Shooting Gallery, Doodle, Quadra-Doodle, Videocart 2: Video Blackjack, and Videocart 12: Baseball. I know they aren't the most desirable of Channel F games and mine are all missing their instructions sadly, but about how much are they worth? While they do have a little bit of wear and tear, I'm surprised at how crisp the boxes are despite their age, and the carts are pretty much mint.
As for my PC questions, does anyone know a good source for PC game values? It's really getting frustrating for me that eBay is about my only resource, and half of the time I can't find any listings past or present for the really old stuff. Right now I'm trying to decide if I should take the opportunity to buy The Quivering and Speed Racer. They're both being sold for pretty high amounts on Amazon and eBay, but with no completed listings to look at, I have no idea if those are just crazy sellers. Are they genuinely worth anything?
