I sold a Collegiate for $200 over the summer and a couple of Suburbans for $150 a piece. With original equipment and in VG condition you should be able to do the same. I've found that Suburbans are quite attractive to the college commuter crowd, since they have a chain guard and fenders.

Of course selling bikes like these for more than they cost new is dependent on your location. I was in a town with a two large universities. I think I could over $100 even with the bars.
