Under the U.S.-Prussian Closed Mail convention of 1852, the rate established for unpaid letters sent from the Austrian Levant to the U.S. was 40¢ per ½ ounce. This amount was a combination of the 15¢ (6 Sgr) per ½ ounce fee to the German-Austrian Postal Union, plus the 25¢ cents per ½ oz. for the combined Belgian transit fee, transatlantic service and U.S. internal postage. Note that the "20/65" accounting in new kreuzer represents the 40¢ total postage due wherein the "20" new kreuzer (10¢) corresponds to the Austrian Lloyd fee from Smyrna to Triest, and the "65" new kreuzer (30¢) to the Prussian Closed mail rate.
