Hi,
Is really hard evaluate your guitar here. Depend a lot on the finish quality and the playability of the instrument. I recommend you to go to a couple of guitar stores and ask for an opinion to an expert dealer. Do not ask them for a price just on how good the guitar is and if something must be corrected or changed. Surely they will compare your guitar with new brand one. If there is no trustful guitar store around ask to some musician to play your guitar and ask them for how good your guitar is. Then you will have a better idea of what you have.
Few years ago I did a guitar, a Fender strat, by myself buying part by part and then assembly it. The guitar was very good and played OK. Also it was very good adjusted. I put on that guitar no more than $300 and sell it last year by $550.
I hope it helps,

C.A.
