This work was compiled and written by one person. The knowledge and factual information needed for this presentation was learned, in part, from the study of other numismatic and historical works.  The accumulation of individual knowledge is achieved through personal experience and by studying the experiences of others.  With this in mind, I would like to thank the many authors, researchers, organizations, and people who have contributed to my general education.


     My thanks to the American Numismatic Association for its assistance on grading standards and illustrations and to the Combined Organizations of Numismatic Error Collectors of America for its aid in error classification and description.


     The following individuals deserve special acknowledgment for their contributions and encouragement.  They allowed me to "pick" their brains, answered questions, offered advice, gave opinions, shared material, and often pointed me in the right direction when I was lost.  These folks allowed me to spend hours looking through their show cases and stock boxes.  I took up their time and occupied space in front of their tables at coin shows.  Through all of this, they were patient with me.  Most important of all, they allowed me to have fun.
