This is antique, late 19th century, Victorian era, about 1885 - 1890, sideboard server with multi-level cabinets, marble serving top and beveled mirror back with decorative carved panels. It is done with a mix of woods such as burl walnut veneers and oak. This is one of the more unique, less-standard forms of a server buffet and silver chest. The Victorian furniture market is currently slumped. Pieces, even the original period pieces, do not sell for what they used to sell for a few decades ago. The market was further impacted by the Recession. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
