Agent Penn E. Pincher is again called out on a case. It seems that in 1979 the U.S. Bureau of Engraving launched a new one-dollar coin. However, most citizens haven't seen it in several years. This case may be from the cold case files. Agent Pincher examines what money is, how it functions, what makes something money, and the advantages of using money. In the end, the students are asked to explain why the Susan B. Anthony dollar does not receive wide circulation.
