It might be on a drawer inside of a dresser or wardrobe. When you find a manufacturer’s mark, take a picture of it. You can use it to determine who made the furniture and what it is worth by looking through catalogues. Then, show off the mark when you’re advertising. You may have received a certificate of authenticity or something similar when buying the furniture. Save it, especially if the furniture doesn’t have a mark to distinguish it. The furniture’s condition has a big impact on the sale price. If the furniture is dinged, damaged, and worn out, you can’t expect to get a lot of money for it.

If you don’t think your item is worth much, then the appraisal won’t be worth doing. Search for online services that can perform appraisals at a reduced cost.

For a basic price estimate, start with the retail price and subtract 20% to 30% from it. Take off extra for wear and tear or damage. Factor in the demand. Selling high-end furniture often involves waiting for a buyer to come along. You may need to drop the price lower than you anticipate to attract more buyers. Pick a realistic price, but have an idea of what you will settle for. For example, you might decide that your Heywood Wakefield armoire is worth $3,500 but is more likely to sell for $2,000.
