In 1982, the U.S. Mint began making pennies of zinc with a copper coating. Ingesting zinc can cause problems ranging from ulcers and anemia to kidney, liver and bone marrow damage, according to Sara M. O'Hara, M.D., assistant professor in pediatric radiology at Duke University Medical Center, Durham, N.C. Dr.

The problem is that pennies minted since 1982 are mostly zinc and carry only a light coating of copper, which can be eaten away by stomach acid. The zinc, in turn, can cause lots of problems that include bleeding ulcers and vomiting.
