1930's Thomasville Dining room set with buffet

Hi, I was given my great aunt's 1930's Thomasville dining room set with a buffet. I believe it is made out of chestnut wood. It is a beatiful set that I no longer need. I would like to sell it, but have no idea how much to sell it for? It has some minor wear and tear, a few scratches on the table surface and some staining on the buffet.  All of this could be easily resurfaced and the whole set itself is in good condition. It has a "Thomasville" paper tag underneath with the code 202-2. There are 6 chairs with it, one have arms. Thanks for your advice!
