If it is in truly very good, original shape, it may be worth $50 to 100 to a local buyer. The prices of vintage Schwinns have been rising gradually, but there are still alot of them out there. I hate to admit this, but you could probably do best by parting it out on eBay, as most of the components are useful to people fixing up Varsinentals and other classic Schwinns.
