New 200 peso bill coming in September

Goodbye feminist poet Sister Juana and hello to Mexican independence icons Miguel Hidalgo and José María Morelos on the new 200 peso billed slated for distribution in early September.
The reverse side of the bill will feature an image of the El Pinacate y Gran Desierto de Altar Biosphere Reserve, a protected eco-region in the Sonoran Desert.
Banxico’s Alejandro Alegre told the newspaper Milenio that bills are changed for three reasons: to apply more elements that will prevent counterfeits; to make them out of more durable, longer-lasting materials; and to incorporate features that aid the visually impaired and money counting machines in identifying them, for this reason the bills will remain different sizes.
Older versions of the 200-peso notes as well as the older 500-peso bills that were replaced last year remain legal tender. The 20-peso bill is expected to be replaced with a new coin but a timeline has not been announced. MM
