Murphy Chair

My mom found two old wood chairs with a sticker or stamp on the bottom of them that has the Murphy Chair Company logo on it with a chair no. 734 on one and the other chair only has half the sticker on it so the number on it can't be read. We were curious how much its worth if anything? The pictures aren't the greatest and I wasn't planning on posting them on any sites so I didn't take more pictures than the two I have and I really dont know anything about them except for the company they came from.
