You are referring to the Mexico gold 50 Peso. That is the coin known as a Centenario. The first issue was in 1921 and celebrated the 100th Year of Mexico’s Independence. The coin was produced until 1931 and then again from 1944 to 1947. From 1949 -1972 and possibly later, the Centenario was restruck with the date 1947. This is a large and heavy gold coin that contains 1.2057 ounces of gold. Only the 1921 and 1931 issues bring a premium above the gold content.
To find the bullion value for this coin, multiply 1.2057 against the world gold price (see the CoinSite Precious Metals page for current prices).
