Any idea what an SR 12 speed Apline Sport is worth?
 

I don't know a lot about bikes but this is what is on the bike. SR apline sport, Champion #5 , Chrome Molyboen steel seamless PG tubes. Made in Japan. Hand brake says Dia Compe, back gear says Suntour ARX, shifter says Suntour power shift. I'm not sure how to measure a bike but from the pedal in the lowest position to the top of the seat tube is 27". This is a bike for a female. Overall good shape, some minor dings, and some discoloration on silver metal (aluminium?) parts. Here's a basic pic. I have a matching guys bike that I think is 26".

+1.... It looks to be in good shape cosmetically. If it is in good repair, I think it would be worth 150 to 175. If it needs rehab; maybe 50.

I've think it's in good shape. Took it for a short ride to make sure the gears change ok and the tires are holding air fine. When you say 'if it needs rehab' what do you mean? New brakes, tires, gears etc.?
Thanks for all the help guys! Now I just need to find a place to post them for sale and get some good pics.

Things like grease, tires, seats, cables, bar tape will age and decay whether a bicycle is ridden or not; even stored inside. How much of that needs attention varies from bike to bike.
