Milton Bradley TI/99 game variants

I scored a couple of extra TI 99 Milton Bradley game variants(bright blue label on end and on backside, with serial numbers on side. The games are connect four and yahtzee. What are these roughly worth each?

Do they say Gamevision anywhere on the labels? If so then they're worth a little bit more. I don't know how much, though, since I don't keep up with such things. Four of the early MB carts for the TI were labeled as Gamevision carts because that's originally what the system was supposed to be, a game system called Gamevision. MB paid TI to design and build it, but at some point TI realized it wanted to get into the home computer market so they claimed the technology and research as their own and redesigned it into a computer. MB figured out they couldn't afford to fight them for it, so they let them have it. They might have also realized that the system had some problems since the original processor TI was prototyping constantly failed in mathematical accuracy and was dumped for a slower chip. MB stayed on and kept making games for the 99/4A, and changed the cart labels after the first batch was sold out.

They do say Gamevision on them. I know that they are pretty hard to find, as I have found large amounts of TI 99 carts over the years, and this is the first time I have ever found them.

This list: http://www4.ncsu.edu/~awwatkin/ATARI/LISTS/ti99.html
gives Gamevision cart rarity ratings of 6 (Connect Four), 7 (Hangman), 8 (Yahtzee), and 5 (Zero Zap). I've never noticed much of a market for TI label variants and they're all common games in the standard labels. Maybe $20 each if you can find the right buyer?

<edit>Have you tried the Yahtzee game? From what I've read, all the Gamevision labelled ones are defective and were recalled, hence the higher rarity for that title. What that does to the value is anyone's guess.
