I imagine they are well-made and sturdy and look better than those images in person or photographed with different digital camera settings in brighter light?
It would depend on whether I wanted/needed them, they matched my stuff, and whether I was buying off Craigslist or in a furniture shop.
I could see them in an estate sale or on Craigslist for under $100 or even $60, or at a furniture or antique shop/catalog/website for $1000.
I personally probably wouldn’t want to pay over $200 unless someone else (my lady, a business partner, etc) wanted them and thought they were worth it, but I expect a furniture store would ask at least twice that (though it also might sit in their showroom for a long time).
(I could be off though. I have done some furniture shopping in recent years, but I’m no expert by any means. Furniture prices are clearly very subjective though.)
