Dating Antiques is the process of determining the approximate age of an object by examining its construction, materials, craftsmanship, design, patina and provenance. Experienced antique dealers consider numerous factors, including joinery, tool marks, hardware, manufacturing techniques and stylistic features, to establish a likely period of production. While some antiques can be dated precisely through maker\'s marks or documented history, many are assigned an approximate date based on expert knowledge and comparison with similar examples. *Related Terms*\ Antique Identification, Dealer Marks, Patina, Provenance, Restoration, Style.
