1957 Mexico Gold Medallic 50 Peso Constitution Centennial BU

---

In 1957, Mexico marked the one hundredth anniversary of its historic 1857 Constitution with a remarkable gold commemorative issue. Struck in 0.900 fine gold, this 50 Pesos medallic coin contains 1.2057 troy ounces of precious metal. Together with its smaller 10 Pesos counterpart, this issue saw a combined mintage of 73,000 pieces, making it a distinctive mid-century release cataloged by numismatists as KM-M122a. The obverse design presents a standing female figure holding a book, set against a backdrop that features a map of Mexico and a shining, radiant sun. The inscriptions on the piece commemorate the first centennial of the constitution, referencing the years 1857 and 1957. On the reverse, the coin displays a detailed representation of the interior of the Chamber of Deputies, the legislative assembly where the nation's laws were debated and forged. This side highlights the constituent congress of 1856 to 1857, capturing a pivotal moment in Mexican civic history in brilliant uncirculated condition.
