[QUOTE="johnmilton, post: 24825413, member: 101855"]You are mixing die variety numbers with different series. Sheldon numbers cover early large cents from 1793 to 1814. Newcomb numbers cover middle and late date large cents from 1816 to 1857. Cohen numbers cover half cents from 1793 to 1857 with the great rarities, mostly in the 1840s excepted.[/QUOTE]
