This is an antique, late 18th to early 19th century, Queen Anne drop leaf table with pad foot gate legs that opens to a round top table. The wood is likely cherry, though in the images it also appears like mahogany. The wood appears to be hand-hewn, the screws, with off-center slots were likely hand forged. If you were to remove one of the screws for a bit, a hand forged screw will have a blunt tip, not pointed, and irregular threads. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
