US Conversion rate 1 US cent = 5 goldcentimes (during 1949 the US conversion rate changed to 3 goldcentimes)
Swedish conversion rate 1 goldcentime = 1.7 öre
US handstamp shows amount to pay in goldcentimes, normally double deficiecy.
In Sweden the indicated amount was multiplied by 1.7 rounded up to nearest 5 öre and marked on the item. The amount due was normally paid by affixing stamps on the item.
Customs fees 85 öre (rate period not known),
stamps probably affixed on the parcel. The postal rate books list two different
customs fees. One lower rate if custom house porter fees (dragarpengar)
are paid and a higher rate if no such fees are paid. Both these rates are
lower than the fee on this item so the rate paid here is most probably
the lower fee (which was 30 öre 1 Jul 1948 to 31 Mar 1959) + the custom
house porter fee.
