The eventual valuing and sale of your guitar will involve a few primary characteristics of the guitar and the market it is being sold on: the year of production, the exact model of the guitar, the condition that it is in, the originality / rarity of the batch that it was released in (this includes any unique defects a guitar might have) - sometimes even the color can have a considerable effect on the overall price of a guitar, whether to its advantage or to its detriment.
