What are the key dates to the 1949-1980 Mexican silver onza coins? And were these coins ever used in general circulation?
Go to the bank of Mexico site when it opens select in English unless you speak and read Spanish the mintages are listed.
I don't think so at all. Mexico has their own money but ours has always been worth more as far as I know. Mexican Reales were used at one time in general circulation on both sides of the border, but not the onzas. The link also has some mintage information. http://donbailey-mexico.com/index.shtml
