No year, because U.S. coins are currently made almost entirely of copper.
Nickels are 75% copper; dimes, quarters, and halves are 92% copper; and dollars are 88% copper. The only coin that is NOT mostly copper is the cent, which is 97.5% zinc.

However, all Lincoln cents prior to 1982 are 95% copper, and all circulation Lincoln cents dated 1983 and later are copper plated zinc.
