How much would all these worth? 

Are you looking for value in Viz?

Usually, every dollar is worth 1000 Viz.

I'll buy your Mario Kart and Pokemon Silver for 25000 Viz.

That was a mistake I tried look for Pokémon silver and I couldn't find it at the time,

also I meant to sell it for davideo7

tronexe98 : If you are in fact intending to sell these to Davideo/Vizzed.com you need to post that in HIS thread that's already created to talk about that.

I'm closing this thread for now, but if you wish to sell the games to other users PM me, and I can re-open it.
