Guitar Question here! please help!?

hey guys, i've recently been clearing out a lot of stuff and found an old guitar. The make is Kimbara and its an acoustic/electric guitar. the label in the hole in the middle says " specially made for FCN-ENGLAND, model no. 3/J made in korea" which after some research indicates that it was made in the late 1980's. I just want an indication of how much this thing is worth, as i cant seem to find another like it :)
