The currency used in Mexico is the Mexican Peso, often symbolized as "$" or "MXN" in international contexts. The Peso has a rich history, dating back to the Spanish colonial period. It is one of the oldest currencies still in use today and has undergone various changes over time, including the introduction of new denominations and a redesign in the late 1990s to prevent counterfeiting. The Peso is subdivided into 100 centavos. As an important currency in Latin America, it is often traded alongside other major currencies like the US Dollar and Euro.
