Facing more negative public reaction, the Coronet cents were redesigned in 1835 by new Chief EngraverChristian 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.
Some 11 years after the large cent was discontinued, a mint employee coined several large cents dated 1868, almost certainly for sale as instant rarities to numismatists. About a dozen and a half of these unofficial issues, struck in both copper and nickel, are known to survive. WIKIPEDIA
