Can't tell much from the photos, but that size vintage box generally goes for $25-$35 in my area. The question is, what are the tools worth? The photo is so grainy and small I don't know what you might have there toolwise, let alone what they might be worth.
You should go check it out, and size up the tools best you can. If they are reasonable quality and useful to you, use your judgement on the value of the tools and make an offer. Be sure to take at least $75 in cash and be prepared to bring the box and tools home.
