US foreign surface letter rate 13 c
Swedish foreign surface letter rate 70 öre
US handstamp shows amount to pay in US cents (normally double deficiency) and US surface letter rate.
In Sweden the indicated fraction multiplied by 70 and rounded up to nearest 5 öre was normally paid by affixing stamps on the item.


Air mail postal card with 10 cent. Correct rate 13 cent. Shortpaid 3 cent. US due handstamp indicates double deficiency 2x3=6 cent and surface letter rate 13 cent. Amount due in Sweden; 6/13 multiplied by Swedish foreign rate 70 öre = 32.31 öre rounded up to 35 öre. Stamps should normally have been affixed on the item but the amount has probably been ignored or the stamps affixed elswhere.
