The Colombian Peso (COP) is the official currency of Colombia. It has been in use since 1810 and is issued by the Banco de la República, Colombia's central bank. The symbol for the peso is $, and it is often written as COL$ to distinguish it from other peso-denominated currencies.

The peso comes in both coins and banknotes. Coins are available in denominations of 50, 100, 200, 500, and 1,000 pesos. Banknotes are issued in 2,000, 5,000, 10,000, 20,000, 50,000, and 100,000 pesos. The design of Colombian banknotes features prominent historical figures, cultural symbols, and landmarks, reflecting the rich heritage of the country.

Colombia's economy relies heavily on exports, particularly oil, coffee, and emeralds. The value of the peso can be influenced by global commodity prices, trade balances, and economic policies. In recent years, the peso has experienced fluctuations due to changes in the global economy and domestic economic conditions.
