What is a bike like this worth

In my area, $75 +-25.

If that's your actual bike in the pic, that's very clean and the basket is nice, if you don't mind waiting a little, I think you could get $200 out of it.

Is it an old bike, or just a neo-retro bike? If it's the former, maybe as much as $200, if the latter, maybe $50 plus whatever the big basket is worth.
