(printed by el Banco de M�xico)
That emission, sent to the circulation May 6, 2013, if it even contains only the denomination of 50 pesos, can be considered as an emission different from the previous one and for that reason begins again by series A.
The process of replacement of the 50 pesos banknote will be progressive waiting their withdraw from circulation because of their deterioration degree.
Throughout the emission, the letters "I" and "O" are not used in the series and subseries in order to avoid the confusion with the digits 1 and 0.
The Bank of Mexico began the circulation of notes of a new banknote of 100 pesos printed in polymer, in horizontal format, commemorating the Centenary of the Promulgation of the Mexican Constitution, 1917-2017.
This commemorative note has legal tender, but people who are interested can keep it in memory of this event. Note that this commemorative note will not replace the one currently in circulation, but coexist with it, and the Central Bank will withdraw once it has completed its useful life.
