Millions of stamp collectors covet U.S. stamps, and the variety of stamps available today is mind-boggling. Therefore, pricing your stamps requires expert knowledge. Experts produce a range of price guides for U.S. postage stamps.

The first volume of the catalog is solely dedicated to information on U.S. stamps.
Specialized Stamp Price Guides
Among the other products offered by Scott Publishing Co. is the Scott Specialized Catalogue of United States Stamps & Covers.

For the beginning stamp collector, though, two more appropriate price guides for U.S. stamps are recommended by the Scott website. The Postal Service Guide to U.S. Stamps, published by the U.S. Postal Service, and the Scott U.S. Pocket Stamp Catalogue provide lots of information on prices for U.S. stamps, and both refer to Scott's catalog numbers when identifying stamps.
