Katavolos Leather Sling Chairs

I'm cleaning out a family home and came across these two chairs. I've done some research, enough to know they date to around 1952 and are Katavolos/Littell/Kelley leather sling chairs. There doesn't seem to be any identifying marks on either chair.

One of them has been welded, not so neatly, in the back. The little rubber feet are missing.

Is there a market for this mid-century chair currently? What would be the best way of selling them?

Thanks!
