Historical context
This silver medal commemorates the centenary of the founding of Puerto Progreso in 1971, the main port of the state of Yucatán, on the Gulf of Mexico coast.
Progreso was officially founded in 1871 to give a maritime outlet to the peninsula's production, especially henequen, the fiber that made Yucatán's fortune during the green gold boom. The port replaced Sisal as the region's main shipping point.
Cataloged by Grove as 1121a, this silver piece celebrates the hundred years of the port city. Commemorative medals of city foundings document the country's local history. The striking of these issues was entrusted to medallic workshops or to the Mexican Mint, keeping in metal the memory of Mexican towns and ports.
Description
The Centenario Fundación Puerto Progreso medal, struck in 1971, celebrates one hundred years of one of the most important ports on the Yucatán coast. Worked in silver, it is a commemorative piece that combines a local historical theme with the lasting appeal of precious metal.
Its specifications are clear: 40.23 millimeters in diameter and 30.82 grams of silver. That fine metal content gives it a value floor, but what truly drives the price up is the condition, how small the issue was, and interest in the centenary it commemorates. A medal with no wear and its original case is worth considerably more than one that has been mishandled or aggressively cleaned.
How to identify and value this medal
