US quarters (and dimes, half dollars and silver dollars) were never made of pure silver. Through 1964, they were 90% silver and 10% copper. From 1965 onward, circulating quarters have been produced from 91.667% copper and 8.333% nickel (although some proof coins have been produced of 90% silver in recent years for collectors). Dimes and quarters were changed to copper-nickel in 1965 when the price of silver increased to the point where coins were worth more than their face value. It was possible to go to the bank and get a roll of quarters for $10, then turn around and sell it to a metal dealer for 3 or 4 times that amount. As a result, most silver coins disappeared from circulation. Half dollars were changed to 40% silver in 1965, then to copper-nickel in 1971.

Each coin is worth about $3.24 as of today just for the silver, the actual price depends on the spot price of silver at time of sale.
There are unconfirmed reports of a few 1965 dimes that were struck on leftover silver blanks, similar to the way some 1943 cents were struck on bronze blanks.. IF one exists, it would be valuable because it would have been struck in a metal that had not been used in dimes for well over a year.When the price of silver started to rise in the early 1960s coins started to become worth more for their metal content than their face value. People were hoarding silver coins and selling them to metal dealers who would melt them. You could buy a $10 roll of quarters at a bank and sell it for $20 (or even more) to a metal dealer, for example! As a result the government was taking a loss on every coin minted and there were serious shortages of coins for making change.To stop the losses the decision was made in early 1965 to make coins out of the copper-nickel "sandwich" material that's now used in all dimes, quarters, and halves. For a while in 1965 the Mints struck 1964-dated coins out of silver while the new metals were being prepared, so there is the possibility some silver blanks got mixed in with copper-nickel ones.
There are 40 quarters in a roll equaling $10. Any quarters before 1965 are worth more due to silver content. Anywhere above $1 per quarter on average per quarter made before 1965.
