Apparently, the Argentine economy is so bad, that one province has created a second currency. Its called Chachos, and they can be exchanged 1 to 1 for a peso. Seems strange to me that a province is printing its own money and trying to circulate it when they already have an equivilant currency. Unless this is essentially a way for the province to circumvent central government printing restrictions.
