The peso is the currency of Argentina since 1992, identified within Argentina by the symbol $ preceding the amount in the same way as many countries using peso or dollar currencies. It is subdivided into 100 centavos, but due to rapid inflation, coins with a face value below one peso are now rarely used. Its ISO 4217 code is ARS. It replaced the austral at a rate of 10,000 australes to one peso.

The dollar sign, also known as peso sign, is a currency symbol consisting of a capital ⟨S⟩ crossed with one or two vertical strokes, used to indicate the unit of various currencies around the world, including most currencies denominated "peso" and "dollar". The explicitly double-barred sign is called cifrão in the Portuguese language.
