This is the same design as on J631/P701 except that a star was added to Liberty's coronet.
These were issued in two different sets with the cent J608-J609/P673-P674 and 3 cent J618-J620/P687-P689 and also with the cent of J605-J607/P670-P672 and 3 cent J615-J617/P680-P683. To view the set, click here.
