Antique Couch

this is my mother in law's couch. she thinks it is rosewood from the 19th century.. she got the couch from her mother who lived in alabama. it is in overall good condition, except for the scratches on the back, as you can see in the picture.. and the lining underneath the couch is hanging down. i'm wondering how much the couch is worth so i can sell it for her.. thanks!
