  1. Check the condition of the stamps

    Mint stamps that still have glue on the back are worth more than used stamps. Sort out stamps that have creases or tears, which are worth less than those in excellent condition.

  2. Compare prices online

    Check online auction sites, such as eBay, to see what prices are being asked for the stamps you are interested in. Make sure you are comparing your stamps to stamps in the same condition, as a stamp in poor condition can be worth around 10 percent of the value of the same stamp in perfect condition. Reduce asking prices on eBay by 20 percent to account for the fees charged on the site.

  3. Check stamp price guides

    The key price guide for stamps in the United States is the Scott Postage Stamp Catalog. Check your public library to find a copy, but check the publication date of the catalog before using it. Catalogs that are out of date provide inaccurate prices since stamp values in the United States have decreased since the 1980s.
