Variety Attribution: Obverse-Star 13 is very close to bust. Date is 8 1/2 mm. large and high, 6 has long curved top that touches bust and 1 touches curl.

Reverse-5 berries, the two upper ones have no stems, are close to the main stem and exactly opposite each other like Siamese twins. Center berry below has the longest stem and the lowest berry a very short stem. Point of leaf under right base of I and distant. AME joined with AM solid at base like one piece. Beak comes down on upper side of star point. C in AMERICA is crude and open. E in STATES clearly over A.
