Seventy-one years after its groundbreaking debut, Paper Money of the United States remains the standard reference on American currency. First published in 1953 by Robert Friedberg (1912-1963), the work revolutionized the field when the U.S. Treasury Department granted permission for photographs of U.S. paper money to be printed for the first time. Now in its 23rd edition, this fully revised and updated volume spans 336 pages and features nearly 1,000 full-color photographs of notes from America's greatest currency collections--including the rarest and most historically significant issues, from the earliest years of U.S. paper money to today. Highlights of the 23rd edition include: Comprehensive coverage of Large Size Notes, Fractional Currency, Small Size Notes, Encased Postage Stamps, Confederate States, Colonial and Continental Currency, Treasury Notes from 1812-1861, error notes, Postage Envelopes, Postal Notes, and Uncut Sheets Market valuations in up to seven grades of preservation Over 990 full-color photographs for easy identification The universally used Friedberg Numbering System(TM)--the industry standard for cataloging, buying, and selling U.S. currency A complete listing of note-issuing National Banks, including the number of notes known for each Comprehensive signature listings for U.S. currency issues Available in two formats: softcover (11 x 8.5 inches) and hardcover (12 x 8.5 inches) When it was first released, Paper Money of the United States introduced innovations never before attempted, setting the standard for all future works in the field. For the past four decades, Arthur L. Friedberg--Honorary President of the International Association of Professional Numismatists and recognized by Coin World as one of the "Most Influential People in Numismatics, 1960-2020"--together with Ira S. Friedberg, has ensured that this landmark reference continues to serve collectors, dealers, historians, and institutions worldwide.
