The museum hosts over 15,000 rare and unique pieces that make up Argentina’s heritage. The collection ranges from different forms of currency used in the Pre-Columbian territory of the Americas—such as cocoa beans and copper axes—to a significant collection of Spanish American reales and doubloons belonging to the Viceroyalty of Peru and of the Río de la Plata.
In addition, there are historical coins and notes pertaining to the provinces and the Nation, including the current currency.
This heritage also contains elements related to the manufacture of coins and notes, such as sketches, drafts, plaster plates, trials, molds, stamps, sheets, notes sheets, and an archive with original historical documents.
With the passage of time, the museum’s assets have increased through countless third parties’ donations and significant purchases. Such items include, for example, the first national coins of 1813 manufactured in Potosi and ordered by the Assembly of the Year XIII and the Gold Patacón, unique piece minted in 1881, and given as present to the then President of Argentina, General Julio A. Roca.
Some of the strangest pieces include commemorative coins which were authorised for production by a French man who proclaimed himself King of Araucania and Patagonia in 1874, or pieces manufactured by Romanian engineer Julio Popper who, chasing the gold fever in Tierra del Fuego, created coins with tools crafted with his own hands.
