The half cent coin was produced in the United States from 1793-1857. The half-cent piece was made of 100% copper. It was slightly smaller than a modern U.S. quarter, with a diameter of 23.5 mm (0.93 inch). Although it is the lowest face value coin ever produced by the United States, given nineteenth century price levels, it was approximately equal to a dime today, in terms of purchasing power.
Opinion varies as to whether or not this should be considered as a separate type or included in the 1794-97 Type. Q David Bowers in his book on US Type Coins (Whitman 2005) considers this as a single year type coin, so who are we to disagree.
