It's a pretty cool bike. I think the biggest thing going against it is that it's a stepthrough frame. The ladies bikes just don't seem to get as much as mens bikes. The finish isn't that much of a concern; that's "patina" and is appropriate for a classic like that. You should be able to find replacement tires; just make sure you get new tires marked exactly the same (i.e., there is a difference between 26 x 1.75 and 26 x 1 3/4, believe it or not). I've seen asks as high as $200 around here, but I don't think anyone's getting that much for a bike like that. You may try asking that, but be ready to accept an offer of less than $150.
Also, where are you? Market makes a big difference in what you can ask for a bike.
