2008 Lincoln Cent
$0.35
The composition was changed to copper and zinc for coins minted 1959 - 1982, with the weight being 3.11 grams and the diameter being 19 mm with a plain edge. In 1982, the composition was changed to copper-plated zinc with the weight changing to 2.5 grams. This is the same composition used today. The older, bronze pieces are currently in demand because the value of the copper comes close to, or exceeds, the face value.
