Howdy! I am hoping to get some insight on the value of my wife's old grad school bike, which I believe to be a Miss Mercian ladies frame -- based on the serial number (45279), it appears to date from 1979. It was used daily as a commuter bike and had regular tuneups at the campus bikeshop, but it's been sitting in a garage for a decade now. I know relatively little about bikes, so if there's anything else on the bike that can be measured, photographed, or described to get a better sense of value, I am happy to do so!
I have pictures, but since I created this account solely to help determine the value of this bike, I have less than 10 posts and am not allowed to post pictures.
