Copper has never been used as a "filler". U.S. silver coins dated 1964 and earlier are made of an alloy containing 10% copper and 90% silver. Copper is necessary to harden the coins to prevent excessive wear. By itself silver is so soft that the coins would have worn out so quickly as to be impractical for daily use.
Dimes and quarters dated 1965 and later are struck on cupronickel "sandwich" blanks. Halves dated 1965-69 were struck on a silver-copper sandwich. Halves after 1971 are made from the same cupronickel metal as dimes and quarters.
It depends on their dates and denominations.All cents were made of bronze, an alloy of 95% copper with tin and/or zinc.Up till 1964 dimes, quarters, and half dollars were made of 90% silver and 10% copper.Starting in 1965, dimes and quarters were made of copper-nickel, with no silver. Half dollars were made of 40% silver and 60% copper.In 1971 half dollars were changed to the same copper-nickel composition as dimes and quarters.
