The Mexican Real was a historical currency used in Mexico from the 16th century until the 19th century. It was a silver coin that became widely accepted in international trade and was often referred to as the "piece of eight." The real played a significant role in the economy of colonial Mexico and influenced the development of other currencies in the Americas. In 1867, the Mexican Peso replaced the real as the official currency of Mexico. The peso continues to be the country's primary currency today, with its value fluctuating against other currencies like the U.S. Dollar. The legacy of the real can still be seen in the peso's symbol, which resembles the letter "P" with two vertical lines.
