Our money
In Argentina we carry the Argentine Peso (code ARS). It uses the $ sign which is a bit confusing at first. However to make the distinction between Peso and US Dollar we write $ and US$ respectively. Currently the exchange between the 2 is around one on three. 3 Pesos for 1 Us Dollar. We have coins from 5 Centavos (Cents) to 1 Peso. Bills are the 2, 5, 10, 20, 50 and 100 Peso bill.
Let me give you an example of a coin and a bill. You can find more on Wikipedia but that article is not entirely correct anymore. It shows bills and coins which are no longer in use.
Veinte Pesos (20 Pesos)
