Aluminum-bronze alloy Mexican 100 Pesos coin features Venustiano Carranza, revolutionary leader and president (1917-20). The other side features the national symbol of an eagle on a cactus eating a snake.
Due to a 1992 currency reform 1000 old Pesos was converted to one New Peso (~10c U.S.).
Collector value of a coin depends on date, mint mark (if any), number minted and condition of a coin, including amount of wear, any dents, scratches or cleaning as well as collector demand for it.
There were 377.4 million of these minted in Mexico City (Mo) that year and it may be worth about .25 to maybe $2 to a collector depending on amount of wear and collector demand.
