: I have a 60’s gibson c1 classic guitar serial number 262034 anyone know its value? I have been told by guitar dealers that unlike many of the steel string gibson’s the classical guitars did not retain the same kind of value. But, if the instrument is in good shape, I would be interested in paying a couple hundred for it. I already have one, that I just put in for repair. And it would be great to have a back-up. Please email to talk more specifics.
