These used to be J1791-J1793 in earlier editions. Examples were struck as follows: Gold with reeded edge J1965/P2032. This used to be J1793A in earlier editions. Seven examples are known supposedly representing 7 different die states and are ex Col Green, Boyd? (see B.G. Johnson 9/27/43 invoice), Farouk, 54 ANA, 57 ANA, Sloss, 79 ANA. Gold with plain edge J1966/P2033. This used to be J1793A in earlier editions. Two examples are known supposedly representing 2 different die states and are ex Col Green, Boyd? (see B.G.
