Looking for Appraisal for Possible Antique Federal Back Shield Chairs

Hi, these chairs are in okay condition,  I believe they have there original stain and resin.  The base of the chairs are very sturdy, plus the seats seem to have the original upholstery and cotton cushion underneath.   The bottom of the seats are wood.  Also, the chairs have a few chips, scratches and a littel white paint drip on one of the back shoulder of a chair, but with a little restoration these chairs can look back to their original condition.  

If anyone has any information on the age or value of these chairs, it would be much appreciated.

Sincerely,

Micahel
