Here's one on siege coins with particularly interesting numismatic aspects. -Editor

"The Pennsylvania Association of Numismatists (PAN) is dedicated to promoting coin collecting by sponsoring educational lectures. Dr. Korchnak has a Ph.D. in Philosophy from the University of Pittsburgh. He is a long-time member of the PAN organization and a devoted coin collector and researcher. His book, Siege Coins of the World 1453-1902, is the definitive reference work of the subject. His presentation tells the stories of some of the most unusual numismatic issues ever struck."
