Cherry Picker's List:
1839 The variety without drapery at Liberty's elbow is worth 2-10 times the variety with drapery.
1840 Struck at the New Orleans Mint using a reverse of 1838 without a mint mark.
1842 The date comes in small and medium versions and the reverse comes with small and large letters.
1842-O These come with Small Date and Small Letters (Reverse of 1839) or Medium Date and Large Letters (Reverse of 1842).
1844-O The double date variety has the original date cut way too high into the die.
1845-O One scarce variety lacks the drapery at Liberty's elbow because of over polishing of the die.
1846 Look for the rare 1846/5 overdate. Date sizes vary and one interesting variety had the 6 of the date punched into the die horizontally, then corrected.
1846-O Date sizes vary; the "Tall" date is the tougher one.
1847 Look for the very rare 1847/6 overdate.
1853-O None were reported to have been minted.
1855 Look for the rare 1855/1854 overdate.
