Will you go on a treasure hunt with me?

An acquaintance, who has absolutely wonderful taste in furniture, is moving and down sizing. She sold me these chairs. I know I got a good deal, but I’m trying to figure HOW good of a deal.
I’ve been googling, but not coming up with a perfect match. Some of you guys are real connoisseurs, so you might know some key words I don’t.
What do you think they’re worth? I can’t find a maker’s tag.
Here are the chairs.
