1970s Ladies Elan 3-speed, value?

Somebody put this out on the curb on one of Winnipeg's Free Give Away weekends.  I couldn't believe they just chucked it out. All I had to do was lube the cables and replace tubes and tires (badly cracked).  It's the Ladies Elan with 3-speed Archer hub, in that dark olive green.  Very good condition.  What would be a reasonable value?   Even though I'm a guy, I ride this bike all the time.  Very smooth, great for leisurely riding.  I'll get pics up tonight.
