Denominations of the Peso
The peso paper currency comes in denominations of 20, 50, 100, 200 and 500 pesos. The coins come in denominations of 1, 2, 5, 10, and 20 pesos, and smaller centavos (100 centavos = 1 peso). Locals may take U.S. dollars, but they will later have to pay a fee to exchange for pesos, so it is highly recommended that you shop with pesos.
