United Nations New York Stamps
Stamps for use at United Nations New York World Headquarters are denominated in U.S. dollars and cents. U.N. New York postage rates correspond with U.S. P.S. postage rates, so a letter mailed to a U.S. destination from U.N. headquarters in New York cost 29-cents in 1993 and costs 49-cents in 2014. These stamps are all inscribed "United Nations."
