Are these chairs more valuable then  

Can anyone tell me if the La Fonda legs on these chairs are valued more then the standard Herman miller legs. I have a set of 4 chairs. One has a leather seat cover and the others do not. One of the chairs was covered but was so beat up and pulling away from the fiberglass that I just took it off, but still have it. So the fiberglass is much cleaner and shinier then the rest. The back side of that particular chair is also red.
The leather chair has a small puncture about 1/8" slit. So small, I am unable to take a picture of it. Otherwise this chair is in great condition.
Thanks for your help!!!
