I would be stingy on that bike myself. The World model is essentially an asian built Varsity. Bottom end bike. Sold one earlier this year for $90.
As far as year, just do a search of the forum. Someone has a site with all the Schwinn brochures from the 1980s. And all of your components have date codes, which can be looked up on the vintage trek site.
