Above is my copy of the second printing of Valentine's 1924 work on Fractional Currency. Jerry provided the above image of Valentine's New York Numismatic Club President's medal, and Pete provided the following entry on Valentine from his American Numismatic Biographies book. Thanks, gentlemen!

By the way, the latest version of Pete's book is still available on the NBS web site, and your input is needed. Are you listed? If so, please review your entry for accuracy and completeness. Are there any mistakes or important omissions? You can access the book here:American Numismatic Biographies(www.coinbooks.org/resources/anb_2010.pdf).
