The United States large cent was a coin with a face value of 1/100 of a United States dollar. Its diameter varied between 27mm and 29mm. The first official mintage of the large cent was in 1793, and its production continued until 1857, when it was officially replaced by the modern-size one-cent coin (commonly called the "penny"). Facing more negative public reaction, the Coronet cents were redesigned in 1839 by new Chief Engraver Christian Gobrecht. This last major change to the coin updated the obverse by giving Liberty a slimmer, more youthful appearance. Minor tweaks continued through 1843, and the 1843 design prevailed through the end of mintage in 1857.
