Value is determined by a number of factors including age, condition, documentation, etc. To get started, look up the the NRA Condition Grading Definitions For Antique Firearms. You can find these by using the Google search form to the right.
To get a reliable estimate of the value of your gun, see a professional appraiser. For something more simple, get yourself a guide book.
Of course, ultimately the value of anything is what it is worth to individuals. What is it worth to you? What is it worth to an individual potential buyer. The gun may be worth more to you because it has sentimental value, e.g. it was your grandfather's gun.
