Yes. The composition of the Lincoln cent was changed during 1982 from 95% copper/5% zinc to 97.5% zinc/2.5% copper. The weigh thus reduced from 3.089 grams to 2.500 grams (or, alternatively, it went from 147 cents per pound to 181 cents per pound.
Two notes: 1 - Both varieties were produced in 1982. 2 - In 1943, cents were produced from steel coated with zinc which weighed 2.700 grams each (or 168 per pound).
