How do I know if my antique lamp is valuable?
Lamps are often more valuable when left in an original condition with most or all the original parts.

Clues in the Cord
In an electric lamp, the cord often reveals the clue to the lamp’s age, unless the cord has been replaced. Inspect the cord; if it looks old, the lamp probably is as well. The metal prongs on the plug are likely the same size, rather than one end that is larger than the other.
How can you tell if a lamp is bronze?
One simple test is to apply a magnet to the artwork and see if it sticks there. Iron is highly magnetic, and you’ll feel the pull in the magnet. If you set a magnet on bronze, it’ll fall off. Also, watch for patches of corrosion, because bronze doesn’t rust.
How can I tell if my lamp is brass?
Solid brass is not magnetic. If the magnet sticks, the item is usually steel or cast iron, with a brass plating. If the magnet does not stick, you can test further by scratching a hidden area with a sharp tool. If you see a shiny yellow scratch, the item is likely solid brass.
