Among the fifteen varieties known of the 1820 Large Cents, three are Overdates.  All three come from different dies.  Newcomb 1 is known as the Large Overdate (referring to the size of the date); Newcomb 2 and 3 are Small Date Overdates.  PCGS recongizes any of these three varieties as overdates.

Of all the 1820 Major Variaties, the Small Date is the least common, followed by the 1820/19 Overdate.  The most common Major Variety, by far, is the Large Date.
