I'm thinking of selling some Super Nintendo games that I no longer play. Could someone give me a reasonable estimate of what I should expect to receive if I sell these AS A LOT. I want to sell them all together.

GAMES:
Mega Man X
Nosferatu(rare snes game)
Tetris Attack
Mighty Morphin Power Rangers
Beavis and Butthead
The Death and Return of Superman
Winter Extreme Games
Wrestlemania The Arcade Game
Weaponlord
NBA Jam
Mortal Kombat 2
Ultimate Mortal Kombat
and also my Mortal Kombat 2 Code Book

thanks
