Circulating state quarters minted at Philadelphia (P) and Denver (D) are made of copper-nickel and don't have any silver at all.
Beginning in 1992, some proof-quality State Quarters were struck in 90% silver for sale in special "Prestige" sets. These carry an S mint mark and are intended for collectors and investors, not for spending.
Each of the new SILVER quarters struck in San Francisco (States, Territories and National Parks) weighs about 6.250 grams and is 90% silver. A quick calculation tells us that each set of 5 of these new quarters will contain just short of 1 ounce of silver (6.250g x .90=5.265g silver per coin. 5.265g=.19oz. silver. .19oz x 5 coins = .95oz. silver per set of 5) This is not EXACT but close enough for most people.
Hope this answers your question a little better.
1932 - 1964 Silver Quarter is 90% silver Quarters after 1964 are copper nickel clad, there is no silver. only the 1/2 dollars or "50 cent" pieces from 1965-1970 are 40% silver. There was a 1976 silver quarter as well as the proof silver state quarters.
There aren't 112 proof state quarters. There are only 50 proof state quarters, (along with 6 in the DC/US territories). Unless you are meaning you had both the clad (copper-nickel, common) proofs and the silver proof sets. But just about every clad US proof state quarter is worth about $1 or so, silver proof quarters go for about $7-8 or about fifty cents or a dollar above melt value individually.
No, pure silver is too soft for most circulating coinage. All silver US quarters have been alloys around 90% silver and 10% copper. Canadian quarters were sterling silver at first (92% silver) then reduced to 80% silver, then to 50% silver than finally silver was fully removed.
