Lot no. 6805

1890, Lot with two 1 cent US postal cards to Sweden. The first from Philadelphia december 17th to Arboga charged correctly with 2x 5 öre Postage due. The second from Marlborough April 15th to Gothenburg incorrectly charged with 3+5 öre Postage due by simply using the wrong equivalent of 1 ctm=0,8 öre which was valid for letters only.
