The Mexican Peso has been the countries primary form of currency since the early 1800’s and it was first issued to Mexico by the Spanish Empire. A peso literally means weight in Spanish and was a saying of how much gold or silver “weight” a person had. The new peso was introduced in 1993 after it remained unstable for some time after the oil crisis in the 70’s. At the time a new peso was equal to 1000 old pesos. The Mexican Peso has gone through many iterations and its most current form is now the series F.
