Hi all... I'm brand new here and I'm curious to know a couple of things about my Martin 00-16C. It was given to me as a gift in about 1963, and is still in near perfect condition. It also has the original hard case it came in (although the case has some splits along a couple of the seams). Does anyone know what it might be worth? I'm probably interested in selling it, as I haven't played it seriously in years.
