75% copper and only 25% nickel, the same composition used since 1866 except during WWII.
The only US nickels that contained any silver were special "war nickels" minted from late 1942 to 1945. These coins are 56% copper, 35% silver and 9% manganese.
You can melt them but you won't get any silver. All US nickels except special "war nickels" made during 1942-45 are struck in the same alloy of 25% nickel and 75% copper.
Since 1965 US dimes have contained a small amount of nickel in their outer cladding, amounting to 8.33% by weight. The rest of the cladding an the coin's core are copper. Up to 1964 US dimes were 90% silver and 10% copper.
Current US dimes are made of a "sandwich" composite consisting of a solid copper core clad in outer layers of an alloy of 25% nickel and 75% copper, for an overall mix of roughly 92% copper and 8% nickel. Until 1964 US dimes, quarters, half dollars and dollars were struck in an alloy of 90% silver and 10% copper. Except during WWII, US nickels have always been made of the same 25% nickel / 75% copper alloy, but they're solid metal rather than clad.
A US quarter is primarily made of nickel and copper. It is composed of approximately 91.67% copper and 8.33% nickel.
Currently, the US dime (and the quarter and half-dollar) is copper-clad and is 91.667% copper and 8.333% nickel. Prior to 1965 (that is, in 1964 and earlier), dimes (and quarters and half-dollars) were 90% silver and 10% copper.US dimes dated 1964 and earlier are made of an alloy of 90% silver and 10% copper.Dimes dated 1965 and later are made of copper-nickel over a copper core. They do not contain any silver.

All quarters from 1796 to 1964 are silver and 1965 to date are copper-nickel
US quarters were not made of silver in 1965, but rather of copper-nickel. The last silver quarter made for circulation in the US were produced in 1964.
It's worth 5 cents.
They were minted at Philadelphia, Denver and San Francisco. They were minted in 1964.
US quarters didn't contain any nickel until 1965. 1964 and earlier quarters were made of an alloy of 90% silver and 10% copper. Please see "What is the value of a 1941 US quarter?" for more information.
US dimes were 90% silver through 1964. In 1965, the US shifted to clad coinage (75% copper, 25% nickel) for circulating coinage.
None. Please don't assume that because a coin is old it has to be made of silver. All US nickels except special "war nickels" made during 1942-45 are struck in the same alloy of 25% nickel and 75% copper.

The last silver quarters were dated 1964. Your coin is made of copper-nickel and is worth 25 cents.
The only US nickels that ever contained any silver were those struck between 1942 and 1945, when nickel was a strategic war material. "War nickels" were about 35% silver with the rest made of copper and manganese. Otherwise, any nickel you find will be made of an alloy of 75% copper and 25% nickel. So if you find, say, a 1957 or 1964 nickel in change feel free to spend it. It's not worth anything special.
