What type of money does Monterrey use?

Answer 1

The peso is the currency of Mexico. The symbol used for the peso is "$", which is sometimes annotated Mex$ to distinguish from U.S. dollars. The current ISO 4217 code for the peso is MXN; prior to the 1993 revaluation (see below), the code "MXP" was used. The peso is subdivided into 100 centavos, represented by "¢". The name peso means weight in Spanish.
