It depends. How many shafts? Size? Weight? Condition of all? Does it roll straight together and apart?
You ask but don't give much info for a good evaluation.
200-500. Depending on all the things I mentioned above. Watch eBay for like cues and see what they sell for and it will give you a decent idea of the value.
I have to say Matt is right on. $300-$450 is about were these are at. Condition plays a big part. It's a tough market for these types of Schon's right now their are just so many for sale.. Very nice cue. GL !
