All of them... except if when you add their values together it makes 100 or more

50,000 pennies equal 500 dollars
US silver quarters weighed 6.25 gm. If you're referring to standard American weights, 1 ounce is 28.35 gm so it would take just under 5 quarters to equal an ounce. If you're referring to silver weight, the coins were 90% silver (i.e. 5.625 gm of pure metal) and a troy ounce is about 31.1 gm so you'd need about 5½ quarters to yield a troy ounce of silver.

Yes, there are many silver Mexican coins, however, when compared to other countries, Mexico used lower purity silver in their more modern coins and often times different coins had different cut-off dates for silver. For example, until 1918, Mexican Peso coins were made out of 90.3% silver, in 1918 that was reduced to 80% silver, in 1920 it was reduced again to 72% silver, in 1947 it was reduced yet again to 50% silver, in 1950 it was reduced to 30% silver, and in 1957 the coin was only 10% silver until 1970 when it was replaced with a copper-nickel coin containing no silver. Mexico also has many modern bullion coins struck in silver.
It depends on the denomination.
