I have to go along with the keep it suggestion. I haven't a clue about the guitar in question but assuming it is one of the cheaper classicals, it likely to be worth more to you than to anyone else.
I had a Hondo classical for many years, not a good guitar but it had a nice sweet tone. When my mother decided she wanted to learn a few chords, the guitar found a new home and it was appreciated. I was far happier giving the guitar away than I would have been trying to get a few pounds for the instrument.
