Adirondack Chairs From Old Wagon

About 15 years ago I purchased a pair of beautifull Adirondack Chiars that were made by a local Arizonan Artisian. Documentation with the chairs indicated that they were made from parts of old wagons such as struts, siding, etc. If you examine the chairs it appears to be true. I am ready to part with these chairs, and have been trying to determine a fair price for the pair. The chairs are as solid as a truck, no screws, and in very good condition, except for some weathering, some water staining, etc. If anyone has a thought about this please drop a comment my way. Another question I have is whether it would be best to leave the chairs in their natural state or refinish them.
Thanks for any assistance received and I apologize if this is an inapropriate post. Don’t know where to go for info.
