US dimes and quarters began using copper as a filler in 1965. Prior to 1965, these coins were made of 90% silver and 10% copper. The switch to a copper core with outer layers of copper-nickel was made due to the rising cost of silver and the desire to reduce production costs. This change was part of the Coinage Act of 1965, which also reduced the silver content in half dollars.
