Mexico’s currency is the peso. The “$” is the symbol used for the peso basically the same as for the US dollar since the dollar derived its logo from the Spanish-Mexican currency. The Pesos is one of the top most traded currencies in the world.
The peso was originally the name of the eight-real coins issued in Mexico by Spain. These were the so-called Spanish dollars or pieces of eight in wide circulation in America and Asia from the height of the Spanish Empire until the early 19th century. After Mexico gained its independence in 1821, the new government continued the Spanish monetary system of 16 silver reales = 1 gold escudo, with the peso of 8 reales the largest silver coin. Paper money was also issued, denominated in pesos.
