The new 2025 Scott Specialized Catalogue of United States Essays and Proofs is the essential reference work for collectors of essays as well as trial color, die and plate proofs. This catalogue is being published as a separate book for the first time. This is a softcover book featuring 6-inch-by-9-inch pages in a two-column format. It makes for the perfect companion to the Scott Specialized Catalogue of United States Stamps and Covers.

The United States Proofs and Essays listings, formerly included in the ever-growing Scott Specialized Catalogue of United States Stamps and Covers, are now instead located within this all-new catalog.

275 pages, softcover.
