How much for sealed Game Gear games?

So I found 6 sealed Game Gear games and I would like to ask you guys how much they're worth. The games are:

R.B.I. Baseball '94 - US version
Poker Face Paul's Gin - US version
Caesars Palace - US version, 2000 Majesco re-relase
Super Battletank - US version, 2000 Majesco re-relase
Spotrs Trivia Championship Edition - US version
NHL Hockey - European version, manual in Italian, game in English

Since they're new, i didn't post pictures, but i could if someone wants to

 

I would assume that only the SEGA published non-sports titles are worth anything sealed, I could be wrong tho.

 

They're worth as much as if they were opened.

 

Moving the thread to the proper location.

Really not a whole hell of a lot. Probably less then $5-10 each. There is good reason why you can find those new.

 

Well, that's what i expected. Thanks for replying thou
