I found this on eBay. This guy has a fillet brazed Schwinn Superior frame "new in box" made in 1978. He's asking $200 as an opening bid. What do you folks think? Is it worth $200?

Its beautiful! But the only person that can answer the question of how much it is worth to you is YOU. What are your intentions with this frame? will you be building it and riding it? is it going to be a rolling treasure that will make you grin every time you swing your leg over the seat? That excitement is worth something, is it worth 200 or more to you? will you kick yourself for not buying it because someone tells you that it is only worth 150? will you ever find it again? this is purely an emotional issue, is it special to you and will it make you feel special? However, if your reason for buying it is so that you think you can make money reselling it ... I have nothing to say about it.

They're worth $200 to a Schwinn collector looking for a NOS Superior. It is a lighter and "cooler" frame than the Varsity/Continental, and probably rides much better. It's still no Paramount, but was I think, the model just below it at the time. Pretty sure they're straight gauge chrome-moly, and decently fillet brazed. Looks cool, and if you're a Schwinn lover, an OK buy at that starting price. Only bummer is no fork... Finding an original in NOS matching condition won't be easy.
