Locate the manufacturer's information. The company's name is typically inscribed on a metal plaque or plastic panel located on one or more sides of the table. If your table has a ball-return slot, the plaque or panel tends to be fastened near it.
Measure the dimensions of the table with a tape measure. Note the length, width and height of the table as well as the number of legs.
Record other details about the table. If you know when the table was purchased new or originally manufactured, take note of the year. Also note the type of pockets (leather or rubber), darkness of finish (black stain to natural wood stain), surface type (slate, wood or other) and color of surface felt.
Consult a local billiards and pool table dealer. If they are familiar with old makes, they may be able to suggest a reasonable resale price for your table. Antique shops are also an option. Most shop owners are versed in many types of old goods, pool tables included.
Appraise your table using online resources. Many websites offer free or inexpensive appraisal services. You may also search online auctions or local classified listing sites to see how much is being asked for tables similar to yours. These figures will help you approximate your table's value.
