If you are referring to the fabled 1964 Peace dollars that the Mint struck as a political and financial favor to the silver lobby, they contained the same amount as other standard silver coins - 90%; the rest was copper. In addition they reportedly used the same dies as earlier Peace dollars so they had an identical design.
The price of silver skyrocketed shortly after these coins were minted so they were never released. Supposedly all were melted but reports persist that one or two were hidden and are in private hands. If so, they would be worth millions each.
1964 was the only year JFK halves were made of 90% silver alloy. The composition was changed to 40% silver clad in 1965, and to copper-nickel clad in 1971. A 1964 Kennedy Half Dollar contains .3617 ounces of pure silver. Multiply this by the spot price of silver to get the bullion value of the coin. At the time of this writing, silver was $16 an ounce, making a 1964 Kennedy Half Dollar worth about $5.80
The 1964 Kennedy half has .36169oz of pure silver in it.

All 1964 JFK halves were struck in an alloy of 90% silver and 10% copper. 1964 was the only year for that composition. 1965-70 halves were struck in a 40%-silver clad composition. All circulating halves dated 1971 and later have no silver; they're made of the same copper-nickel "sandwich" metal used for dimes and quarters.
There were no silver dollars issued by the US Mint in 1964.

The 1964 Kennedy half dollar. it was the only year that the coin was made of 90% silver. In 1965 the coin was "debased" to 40% silver, and in 1971 the composition was changed again to copper-nickel.
All the 1964 peace dollars were melted. My guess is you have a 50 cent piece half dollar. Which has 90% silver content also all per 1964 coins were also 90% silver
For 90% silver coins (1964 & before) 10.2537 grams.
Yes, there is a John F. Kennedy silver half dollar but not a quarter. Kennedy half dollars were minted in 90% silver in 1964, and 40% silver from 1965 to 1970. Silver quarters were last minted in 1964 before switching to a copper-nickel composition.
Sorry no US dollar coins dated 1964
