Value is not a lot and chairs would sell better than the table and buffet because they are a simpler style and could be blended into todays homes more easily. Also much depends on the condition of the pieces. Something that needs work will not sell as well as one in good usable condition !! On the chairs , around here, ( and location can mean different selling prices) you might get around $20. each for them, give or take a little !! Table and buffet together,, maybe $150 to $200. for both !! And that is if in good condition !! Other areas may be slightly higher or lower !!
