I usually offer between $15-20 for atari consoles, $20 for the NES, 50 cents per game. I didn't see anything too valuable. Some of them are intellivision. The earthbound game is worth money though. Condition is super important on it, but even the box will fetch a good price. The zapper looks like an Atari XE one, they are a bit hard to find, but it is missing the side decals. Hope that helps. The baseball cards are essentially worthless.
