The definitive reference on U.S. Postage stamp errors has been extensively reviewed and updated since its last publication in 2021.

In the 19th edition of the Scott Catalogue of Errors on U.S. Postage Stamps, which debuts in November 2023, hundreds of values were analyzed and updated, new full color illustrations added, and many new listings appear for the first time.

Listings are identified by Scott numbers and are classified according to the type of major error: imperforates, color-omitted errors and inverts.

Additional information, exclusive to the U.S. Errors catalog, includes known quantities, production details and cautionary notes. Values also are provided for error-like imperforates and printer’s waste.

A detailed overview of freaks and oddities is included for reference.
