The "peso" finds its origins in the Spanish silver coin known as the "piece of eight," extensively used during the colonial period. After the independence of Spanish colonies in Latin America, several countries adopted the peso as their national currency. Presently, countries such as Argentina, Chile, Colombia, Cuba, the Dominican Republic, Mexico, the Philippines, and Uruguay utilize the peso as their official currency, each with its unique monetary system, symbols, and values. The persistence of the term "peso" in these countries reflects the Spanish colonial legacy and the historical significance of this currency.
