This is the first use of obverse 4 and the final use of reverse D, introduced with 1829 LM-4. This obverse die was used for six different varieties, including LM-6, 10, 15, 17, and 18. Very lightly cracked obverse from I across face in front of curls, eventually reaching drapery. The reverse die is lapped with die sinking, causing coins struck from this die to have a concave appearance.
