It varies! For years Mexican silver items were often in the 40-75% silver content range. However, in the past decade many reputable Mexican jewelry manufacturers have begun producing high quality sterling silver which is 92.5%. Unfortuanately it is also a common occurence for the less reputable manufacturers in the country to stamp .925 on silver jewelry when it is not .925. The key is to source your jewelry from a trusted manufacturer or store that is verifying quality through assay testing.
.925 generally marks the silver content in a silver ring, and it heavily regulated in Mexican silver. I would not trust the mark to mean the same on a Chinese ring without seeing a qualified jeweler.
The Mexican Peso featuring Morelos facing right (1957-67) is 10% silver and contains .0514 of an ounce of silver. You might also try a library for a copy of the Standard Catalog of World Coins for pictures, values and lots more interesting info. There are at least 15 other countries that call their currency the "Peso".
The millesimal fineness of Mexican Silver is 950. Which means that Mexican Silver alloy is 95 percent silver and five percent copper. Previously, it was considered to be 980.
It is 90.3% silver and has .7859 troy ounces of silver. However, 1910-1914 Mexican pesos are collector coins with values that exceed bullion prices for all but the most worn examples. While they have less than $20 worth of silver in them, even worn coins can be worth $50 on eBay and values jump into the hundreds of dollars for better grade coins.
