An on-line appraiser said this about these chairs:
They were manufactured around 1875-1880. The tableture in the top crest would be a walnut veneer, burl. The rest of the woods I cannot see in the photo but these are often a mix of cherry, maple and birch. All light colored woods. Many are also all walnut but again, I cannot see the grain pattern.
At auction these would probably have sold around $50 – $75 each but in a retail setting would price at $250 each if in good condition. The seats alone would cost about $175 to have woven.
We are selling these great condition chairs for $500 – well below their appraised value.
The woven seats are all in good – excellent condition. 18″ seat height. Will be hard to find a better set for this age.
