Thirteen stars (symbolizing the 13 original colonies) were added to the perimeter of the obverse in 1838. These were replaced with the legend "United States of America," which was moved from the reverse in mid-1860. At the same time, the laurel wreath on the reverse was changed to a wreath of corn, wheat, maple, and oak leaves and expanded nearly to the rim of the coin. This reverse design continued through the end of the series in 1891 and was changed only slightly in 1892, when the Barber dime debuted. Another variety is the 1838–40 dime minted with no drapery underneath the left elbow of Liberty.
