American Furniture Company Dinning Room Set

This Dinning Room set has 5 chairs that were reappolsterd in the 1990's, a china cabinet in very good shape, a buffet in very good shape, and a dinning room table which has small scrathches on the surface.  Other than reappolstering the chairs it is all original and has never been resurfaced.  This set belonged to my Grandparents and I have had it for close to 20 years.  I found the original paper of authenticity in a drawer of the buffet.  All pieces are stamped with "400". 

I am interested in purchasing a new set and would like to sell this set.

I read the history of American Furniture Company from VA and it is interesting, but gave me no ideas as to value of old furniture.

Any help would be appreciated.
