Dr. Ronald Kohser has been keeping a close watch on coins during his career. According to Kohser, a professor of metallurgical engineering at Missouri University of Science and Technology, it currently costs the U.S. Mint about 1.7 cents to make a penny and around 7 or 8 cents to make a nickel. The amounts include metal content, tools and dies, and labor.
