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").
As a response to public criticism of the Classic Head, the Mint assigned Chief Engraver Scot to redesign the cent in 1816. This newest design enlarged the obverse portrait, giving Liberty a much more mature look (leading to the Matron Head reference), and surrounded the portrait with stars along the outer edge of the coin. The "Matron head" design was modified in 1835 to give Liberty a younger look and matron head cents continued to be made until 1839.
