Numismatic literature refers to written works that focus on the study and collection of currency, including coins, paper money, and tokens. This field encompasses a wide range of materials, such as books, journals, catalogs, and articles that provide information on the history, production, and valuation of various forms of money. These publications are essential for collectors, historians, and researchers interested in understanding the significance of currency in different cultures and time periods. Notable examples of numismatic literature include works by Walter Breen and the American Numismatic Association, which offer insights into coinage and its impact on society.
