I agree your location is a big factor. In Miami with a nicer saddle, not to racy, and a little lemon pledge to make it shine you might get $200 but in Fort Wayne it is going to be below 32 for the next few days it will languish at $50 for weeks. Unless some flipper grabs it to resell in June.
Check you rear wheel. See how the dropout is worn near the front? That is where the wheel should likely be sitting, and I might make shifting smoother for a test ride.
