Los-Nr. 6802

1881, Insufficiently prepaid letter sent April 10th from Falköping to Helsinki (Finland), then returned to sender. The prepaid rate to Finland was 20 öre, thus this letter was underpaid 8 öre (11 ctms). As the Russian kopek was equal to 4 ctms the double missing postage was 2x 11=22 ctms=5,5 kopek rounded up to 6 kopek=24 Finnish pennies, the correct postage due should have been 20 pennies. The letter was returned to sender and should have been charged with double the missing postage, against the rules he was charged 8 öre, plus a return postage of 20 öre=28 öre. Folded up for display.
