Lincoln Cents

When was the last year our Lincoln Cents were made of copper, rather than plated?

1982 is correct but both types were made that year, to tell the difference they must be weighed. .950 copper 3.11 grams. Copper plated 2.5 grams. There are actually 7 varieties for that year plus the proof. They had large and small dates plus the different mints.
