Help! Could you tell me how old this sofa might be and the value?

My great aunts were antique dealers, and had this sofa in their home. It's about 72" long, 32" deep, and 32" tall at the back (18" seat level) I don't know anything else about it. I'm curious how old it might be and where it was made? Could this be the original fabric? Should I worry about insuring it?

I'd appreciate any thoughts people have on it.
