Before selling dolls at a garage sale, check eBay.com for the most recent selling price of particular dolls. While some dolls have little to no value attached, others are rare and collectible, making them desirable to doll collectors who would pay more than an average garage sale customer.
Identify the name, make and type of doll in order to best gauge its value. In addition to eBay, doll values are available in doll or antique price guides, such as Kovel's Antique and Collectibles Price Guide, available at libraries and bookstores. Bring dolls to a local doll or antique appraiser for advice and information.
