If you mean pure copper, no. Quarters were made of 90% silver / 10% copper up till 1964; in 1965 the composition was changed to the current "sandwich" of 75% copper / 25% nickel outer layers bonded to an inner core of pure copper.
If your coin weighs the same as a regular quarter, it's been plated - this is a common high school chemistry experiment. However, if it's thinner than a regular quarter it's possible that you have what's called a lamination error. That happens when the outer cladding on a modern quarter separates from the copper core. Normally that happens only on one side so a double lamination error is fairly scarce; if that's what you appear to have the coin should be inspected in person.
Yes. That was the first year the U.S. minted quarters out of copper instead of silver.
All circulation quarters dated 1965 and later are made of copper-nickel.
1964 was the last year that quarters were struck in 90% silver and 10% copper.
The composition of quarters in the United States changed in 1965. Prior to that, quarters were made of 90% silver. However, starting in 1965, the composition of quarters changed to a mix of copper and nickel, which is still used today.
Circulating quarters were made of 90% silver and 10% copper from 1796, the first year of issue, until 1964. Increases in the price of silver forced the Mint to switch to the current copper-nickel clad composition in 1965. Special 40%-silver quarters were made for sale to collectors during the Bicentennial, and starting in 1992 90% silver quarters have been struck for sale in "Prestige" proof sets. None of these were ever intended for circulation, though.
Since 1965, U.S. quarters have been made of a solid copper core with a copper/nickel coating.
Silver, but they now make quarters out of copper and nickel so if you have a quarter that was made before 1965 keep it!!
Yes. That was the first year the U.S. minted quarters out of copper instead of silver.
Present day nickel, dimes and quarters are composed of copper and nickel.
All quarters dated 1965 and later are made of a "sandwich" of copper and nickel.

Pennies: zinc, with copper plating (not mixed together).Nickels: 75% copper and 25% nickel, alloyed togetherDimes, Quarters, and Half Dollars: Pure copper clad with the same alloy as nickels, for an overall content of 8% nickel and 92% copperDollars: Pure copper clad with manganese-brass alloy.

The outside is an alloy of 75% copper and 25% nickel, with pure copper in the center. Including the core, the coins are about 91.7% copper and 8.3% nickel.
US state quarters are made of a combination of copper-nickel (75% copper, 25% nickel) bonded to a copper core. This composition helps to create a durable coin that is resistant to wear and maintains its appearance for circulation.

US quarters are not typically magnetic. Quarters are made of a combination of metals, including copper and nickel, which are not magnetic.
