The Escudo is a currency used in several countries, most notably in Chile and El Salvador. In Chile, the Escudo was introduced in 1975, replacing the Chilean Peso at a rate of 1 Escudo for 1,000 Pesos. It is subdivided into 100 centavos and is represented by the symbol "$" or "Esc". In El Salvador, the Escudo was the official currency until 2001, when it was replaced by the United States Dollar. The Escudo was also used in Portugal until it was replaced by the Euro in 2002. The currency has historical significance and reflects the economic changes in these regions.
