The currency used in Argentina is the Argentine peso, abbreviated as ARS. The peso has undergone several changes and revaluations since its introduction, reflecting Argentina's fluctuating economic conditions. As of my last knowledge update, the peso has seen high inflation rates, leading to frequent adjustments and the emergence of informal currency exchange markets. The currency features various national symbols and historical figures on its banknotes and coins, representing Argentina's rich cultural heritage. Understanding the peso is essential for commerce, travel, and economic analysis within Argentina.
