What are my clubs worth?

I have a set of golf clubs we dug out of the closet of our new home here in Chattanooga, TN. I would like to sell them, but also (obviously) would like to get a fair price for them. They are lightly used, and none seem to have any dents or dings in them. There is dirt on the PW, and on the skinny#5 club. They are Kathy Whitworth Monogram II, and are made for a petite woman. All are graphite shaft except for the putter. The skinny head clubs are numbered 4-9, and the fat headed clubs are numbered 1, 3, 5, 7. It also has a matching PW and SW, but the putter is a different brand (Align series 3). The bag says "CROSPETE sports" I think. This set also has an extra Callaway #5 fat head club that says "Big Bertha" and "S2H2" on it. That club has its own special little sock cover. Any help would be greatly appreciated. Thank you! FYI, these will probably eventually go on craigslist here in Chattanooga, and down in Atlanta.
