Numismatics Museum "Héctor Carlos Janson", Currency museum in San Nicolás district, Buenos Aires, Argentina
The museum houses one of South America's largest collections of currency objects with over 20,000 pieces from various periods. The holdings include coins, banknotes, promissory notes, and other financial artifacts that document the region's economic development.
The building was constructed in 1862 and originally served as the Buenos Aires Stock Exchange before being converted to a museum in 1941. This transformation marked the start of a new purpose dedicated to preserving and displaying currency history.
The collection displays pre-Columbian payment systems like cocoa beans and copper axes, showing how people exchanged goods before European contact. These objects reveal the economic practices that existed in the region before coins and banknotes arrived.
The museum is located in downtown San Nicolas and operates on weekdays with free admission for visitors. Note that it does not open on weekends, so planning your visit for morning or early afternoon hours on a workday is recommended.
The museum displays rare banknote series featuring Argentine wildlife and documents a special currency period between 1890 and 1935 with historical variations. Those years reveal a fascinating chapter in the country's financial history made visible through the style of money printed at that time.
