was US$15,000; when Alfred H. Caspary sold the same stamp in 1963 the price was $41,000, the highest value ever paid for any stamp at that time (even more than the British Guiana 1c magenta and "Post Office" Mauritius blue two pence and red one penny rarities). An astonishing lore surrounds this stamp: in 1892, one of its earlier owners, Gaston Leroux, was murdered for it by an envious fellow philatelist, Hector Giroux. In the 1963 movie Charade, Charles Lambert placed three valuable stamps on an envelope to hide $250,000 he had stolen, with accomplices, during WWII but kept for himself. One of these stamps is a 3 cent Hawaiian Missionary intended to represent the rarer 2 cent value. The Dawson cover The most valuable of all Missionary items is a cover sent to New York City bearing the only known use of the 2-cent value on cover, as well as a 5-cent value and two 3-cent US stamps. This is known as the Dawson Cover. It was in a bundle of correspondence shoved into a factory furnace around 1870, but packed so tightly that the fire went out (though one side of the cover bears a scorch mark). The factory was abandoned; 35 years later, a workman cleaning the factory for reuse discovered the stuffed furnace, and knew enough about stamps to save the unusual covers. This cover was acquired by George H. Worthington in 1905, then bought by Alfred H. Caspary in December 1917 for $6,100. It has changed hands several more times: the Weill brothers bought it for $25,000 in 1957 for Benjamin Dwight Phillips and eleven years later disposed of it from the Phillips collection for $90,000, in the 1995 Siegel auction it realized a price of US$2.09 million ($1.9 million plus 10% buyer's premium), and in 2013 it sold for $2.24 million to an American collector making it one of the highest-priced of all philatelic items. The Dawson cover, shown on the 2002 Souvenir Sheet (Scott 3694) may be evidence of the validity of the 1850 Treaty of Friendship, Commerce, and Navigation between the United States and Hawaii as a sovereign nation.
