Set of 4 wooden antique chairs

I have a house full of antique furniture and collectibles from my mother's estate.  Both she and her mother were antique collectors.  I'm keeping a few pieces for sentimental value, but I just dont have room for all of them.  If anyone has an idea of the worth of these items and how to best sell them, please let me know.

I've got 4 wooden chairs, all similar, but each unique.  I'd say they are each around 150 years old.  They were acquired in the Leesburg VA.

Good
