Below are the Mexican Peso notes currently in circulation. The 1000 Peso note is a rare find and may not be accepted at all outlets in Cancun. Guard your small change with your life! Nobody seems to have change and you are almost always asked for the odd peso or two to round up or down.
It almost seems to be a competition to see who can break down the larger notes and hoard the highest number of small notes – be a part of it – they will come in useful!
