All 1981 and prior are 95% copper. 1982 had both copper cents and zinc cents coated in copper The beginning of the Zincoln.
In fact here is post on another forum that I Lurk at that explains it better than I can!

Yea, everything 1981 and before are copper. You can try to save 1982 but there is a good number that isn't copper.
