1881, Unpaid mourning letter dated Burlington (USA) July 16th to Willands Wånga. The single UPU rate was 5 cents corresponding to 25 centimes. Postage due was double the missing postage, 2x 25=50 centimes. The exchange post office in Sweden used in this case the conversion tables based on the commercial rate 1 centime=0,80 öre and not the more usual =0,72 öre. Thus the postage due became 50x0,80=40 öre. The letter is opened up for display.
