How can I tell if a piece of furniture is valuable?

To tell if a piece of furniture is valuable, conduct research to see how much similar pieces have sold for in the past. The maker, age, materials, style and type of furniture all impact its value, as does its overall condition. As a result, the best way to get an accurate valuation is often to use the services of a certified appraiser or knowledgeable antique dealer.
