In an effort led by Len Augsburger in 2009, NBS compiled and published a list of The One Hundred Greatest Items of United States Numismatic Literature: A Survey of the Numismatic Bibliomania Society.
Yeoman was being modest - his Guide Book of United States Coins is 24th on his list - it came in 4th on the NBS list of 100. And many of the 100 titles had yet to be written in 1959, including the #1 item, Walter Breen's Complete Encyclopedia of U.S. and Colonial Coins.
Exercise left for the reader: how many of 1959's top 29 are among the 2009 top 100?
Of course, the criteria for the two lists are different - Yeoman included world numismatics while NBS focused on just U.S., and the NBS nominations included auction catalogs and periodicals and more in addition to books.
