A couple of NES game prices

[your average simian]

Hi. A friend gave me a bunch of old NES games and told me to sell them for as much as possible.

Can I please have your opinion on how much I might get from these games and should I sell them all in one big bundle or is there one I might want to sell separately to get more money?

Mario Bros.
Super Mario Bros.
Super Mario Bros / Duck Hunt
Ice Climber
Volley Ball
Tennis
The Legent of Zelda
Chip 'n Dale Rescue Rangers
Probotector (Contra)
World Class Trac Meet (NTSC)

Only cartridge. All of them are in stunning condition. Absolutely mint. All the games (with the exception of WCTM) are European versions.


Also, I was wondering what version is the Mario Bros. It's obviously euro but I haven't seen that cover art anywhere before. Does anyone know?


I am also tasked to sell the rare NES game Stadium Events (unfortunely the PAL version, otherwire I'd be feasting right now.) For how much should I sell it for? Only cartridge, condition absolutely stunning. German text on the cover.
