Large wooden (don't know what type) rocking chair originally built without hardware I would guess (arms are still attached via wooden dowels) but seat cracked and has a glaring repair on bottom. A couple of very old screws and nails have also been added to help keep it together. Crack along main back panel was also there when purchased. Floor to seat is 16 inches tall, floor to arm top is 27.5 inches, 41 inches from floor to top of the back of the chair, seat is 20 inches wide and 19.5 inches long.
My aunt said that my grandfather purchased it for her back in the 1970s and the back was cracked then but he still paid a couple of hundred dollars for it - quite a bit for my frugal grandfather.
This is an antique, late Victorian era, circa 1900, Arts & Crafts era, Mission style, quarter-sawn oak large sized rocking chair. The Arts & Crafts era or movement was marked by a return to craftsmanship in response to mass production by machine; hence the use of mortise and tenon type joinery for the construction of this rocker. Unfortunately, rocking chairs are a bit of a 'hard sell' on today's market, and the condition issue does further impact the value. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
