My guess is that they are among some of the last Western Flyer bikes produced--maybe 1980's-90's--and very plain. I don't know if a year can be nailed down any further than that. Sales ended in 1998.
Location impacts value, but I'd be surprised if those bikes raised $75-100 in most venues...and less for the ladies. They just aren't that old or that unique.
Some of the last CWC/AMF road master bicycles built in the U.S., in original condition/configuration, (and a pair at that).
The vinyl grips are Hunt Wilde's made special for Western Auto.
Maybe someday they would make a nice trophy, in a couple's garage.
