That's a nice example of a vintage schwinn.
If you're in a major market, you should be able to get $300 on CL.
Be prepared to field tons of low-ball offers, trades, and requests to ship.
I just sold a nice vintage Chicago Schwinn BMX on CL. It took 4 months for a serious buyer to come though and I'm in Chicago.
The buyer was a collector of vintage Chicago schwinn BMX and paid the asking price. Interestingly, he was from the East coast and was in town visiting family.
