How much in your area?
I would be interested to know how much these would go for in your area at auction, or retail. They were sold as a pair and are black framed womb Knoll womb chairs in good structural, poor cosmetic, condition. The brown chair is 1950s, original fabric, with a missing back cushion (that looks like the ottoman cushion) The orange chair is probably 1950s with a 1960s-70s Knoll fabric recover. They need to be refoamed and reupholstered. I know what they went for here, but there seems to be a huge regional variation for this sort of thing.
