How do I know if my lamp is valuable?

To know if your lamp is valuable, first try to determine who made it. Look for stamps and stickers in inconspicuous areas, such as on the bottom of the base or on the back of the base near the cord. Once you have determined the maker, you can use trusted online resources to see what similar lamps have sold for in the past. Because the condition of your lamp and current market conditions can also impact the value of a piece, you may want to have your lamp professionally evaluated by an expert like a certified appraiser or knowledgeable antiques dealer.
