What this coin looks like (obverse, reverse, mint mark location, special features, etc.): One major variety of the 1839 Coronet Head Large Cent (Penny) includes the "Head Of 1838" design of the portrait of lady liberty on the obverse of the coin. This is the older design from the previous year which lacks the additional lock of hair that was included on the forehead of the liberty in the newer 1839 designs.
Depicted below is an example image showing the differences and comparisons between all 4 varieties of the 1839 large cent. Note how the hair line changes relative to the "LIBERTY" crown and the style of the hair. Also note the additional features unique to each variety pointed out by the arrows.
