Antique Lion head dinning chairs

These chairs are beautiful, they are all  (4) hand carved dining chairs. the head rest has a lion's head, they also have barley twist on the side and legs, the 2 front legs have caster.

I would like to find the value, since they do need a bit (minor) repair.  The back of a couple of chairs is loose, needs readjusting. they were professionally reupholstered approx.5 years ago.
