Super nice complete examples of this kind of bike, and yours is very nice, very complete and original, top out at maybe $150. It's not a boy's bike, it's not a Schwinn, but it's of the classic era and it's a good unmolested example.
More in big cities, less in rural areas, more if you can figure out what year it is and maybe find a buyer looking for a "birthday bike".
Be very careful if you try to clean it up- the decals are likely to be pretty fragile. Clean the chrome up with Never-Dull or a good automotive chrome polish and leave it as original as possible.
Take good daylight, outdoor pictures of it from all angles and details and put it up on Craigslist or Ebay if you're looking to make the most out of it.
It would make a nice addition to a bike collection, but it's not the first thing people are going to have in mind when it comes to '60s musclebikes.
