International Association of Financial Crime Investigators: Some of the earliest financial crime fighters were members of the U.S. Secret Service, which was created to fight counterfeiting during the Civil War. Today, if you suspect someone of shady money business, you can contact a member of the International Association of Financial Crime Investigators, which provides information to consumers to protect themselves against fraud and other financial wrongdoings.

American Numismatic Association: Did you know that the U.S. Bureau of Engraving and Printing produces roughly $907 million worth of currency a day? This is probably no surprise to members of the American Numismatic Association, which promotes the study and collection of currency. ANA members can learn the finer points of counterfeit detection and currency grading during one of the association’s sponsored seminars at the Florence Schook School of Numismatics.

American Institute of Certified Public Accountants: We wonder if the American Institute of Certified Public Accountants ever counted comedian Bob Newhart or jazz musician Kenny G, both of whom started out in accounting, among its members. With almost 386,000 members in 128 countries, AICPA develops and grades the Uniform CPA Examination, which serves as the only licensed qualification in accounting.
