Those are going for 500 to 1200 approximately, with condition, completeness and originality being the deciding factors.was told that they were 68 and 69 only.i think 68 had s2 rear wheel and s7 front with a krate style shifter.69s seem to be thumb shift and s7 wheels front and rear. Krate style shifters seem to get more than thumb shifter models.i am no expert, just sharing what I learned when shopping and purchasing my 68.that is a nice example.great silk screen and decals.i would not clean more than dusting off if it was mine.i would probably ask $800.00 or best offer if it was in cali.id take no less than 5 or 6 hundred for it.again, just sharing what I have learned recently, not a schwinn pro.hope it helps!
