Patagonia is not a country. It is an area that is partly in Chile and partly in Argentina. So there are two currencies in use in it. The currency of Argentina is the Argentinian Peso and the currency of Chile is the Chilean Peso.
The Patagonia region is shared between Argentina and Chile, so they will most likely use whatever currency they use in Argentina, or in Chile, depending on what part of Patagonia you are talking about.
