If you have a piece of art that has belonged to your family for years, it's easy to begin wondering what the piece may be worth. This can especially be true if you've heard your parents or grandparents talk about its purported value. The best way to get an accurate sense of the piece's current market value is by seeking out a reputable and experienced art appraiser. You can find such an individual online, or by contacting a local art gallery to determine if it has appraisal services.
