In 1989, Henry Morris, director of Bird & Bull Press, produced and published the book Trade Tokens of British and American Booksellers &Bookmakers. The book was accompanied by a heavy die-cut board folder containing eleven different copper tokens minted by individual booksellers &bookmakers especially for this book. The Graphic Arts Collection and Numismatics Collection have jointly acquired the dies and proofs used in theproduction of the these bookseller tokens.

Morris's original dies, medals, and proofs are housed in a mahogany box with a token inset on the top cover, along with a metal plate inscribed "Original Dies for Bookseller's Tokens, Bird & Bull Press."

The participants whose tokens are included here are: Bird & Bull Press, The Book Press, Dawson's Book Shop, Detering Book Gallery, Enterprise Books, Joseph J. Felcone, Kater-Crafts Bookbinders, George Frederick Kolbe/Fine Numismatic Books, G.T. Mandl (English papermakers), Iris Nevins (marbler), and Oak Knoll Books.

The tokens (with nine duplicates), along with a rough flan, were made under the supervision of Meyer Katz at the Unity Mint in Ambler, PA, from dies engraved by Kenneth Douglas at the Green Duck Co., in Olive Branch, MS. The set of 11 tool-steel dies (22 pieces), now coated with a protective lacquer, cost Morris $9800 in 1988, which he considered a bargain.
