Real hard to say - I sold my '57 Goldtop reissue (2005) for €2200 - which is more than I bought it for. It had the neck through and was mahogony with the aged hardware and burstbucker pups, 100% mint - never played it because I didn't like the feel. One good thing about LP's is that they actually go up in value if taken care of. Try the guys at homerecording.com/bbs - there are lots of LP users and fanatics there.
