Q. David Bowers (edited and updated by Mike Sherman): In 1838 stars were added to the obverse of the Liberty Seated design. Otherwise the motif is similar to the 1837 and 1838-O Liberty Seated pieces. From 1838 thorough 1859 many different varieties were produced, including some struck at the New Orleans Mint (and bearing a distinctive O mintmark on the reverse). Early issues lacked drapery at Liberty’s elbow. There are some scarce dates and varieties within the range, notably 1846, 1849-O, and 1853-O without arrows at date, but there are enough common varieties that it is not difficult to acquire an example in nearly any desired grade from Good through About Uncirculated. Uncirculated coins are naturally scarcer, but should not present an undue challenge to the collector.
