This is a late 19th century, about 1890 - 1895, Victorian era, sideboard with stipple carved details on the doors and beveled mirror back. The design is lightly influenced by the Renaissance Revival style that was popular during that period. This would have likely been part of a larger dining suite with matching china cabinet, dining table and chairs. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
