Keep an Eames lounge and ottoman with questionable upholstery?

TLDR: I'm considering selling an Eames lounge and ottoman and getting a couch. The leather seems fake to me though.

UPDATE: It's leather, just crappy leather. Still a very comfortable chair.

I have a series II Eames lounge and ottoman. They were refurbished at some point before I got them, and I'm not sure what the deal is with the upholstery. To look at it you'd think it was leather, and I never even thought about it till recently. I unzipped the cushions to further inspect, and I'm pretty sure it's not leather, unless there's some finish I am unfamiliar with.

In the end it's just a chair, and it's very comfortable and I enjoy sitting in it, but I'm wondering who I could sell it to knowing it's not leather. Are there pros to it not being leather (for me, not from a sales standpoint)? What would I even charge if I sold them? I know there's a market for knock-offs. These are legit, however, with the original wood and bases (other than updated cushion clips), just with non-leather upholstery.
