VERY FINE. AN EXTREMELY RARE HAWAIIAN AND UNITED STATES MIXED-FRANKING COVER.
With 1976 P.F. certificate stating "genuine", but followed by 2000 P.F. certificate stating "it is a genuine usage of the U.S. stamp, but decline opinion as to whether the Hawaiian stamps originated." To authenticate this cover, the three stamps were carefully removed, revealing that the paper surrounding the stamps has aged consistently, and the spaces where the paper has not been exposed precisely match the dimensions of the stamps (see photo). In our opinion, this conclusively proves that the two Hawaiian stamps originated on the cover. The Honolulu post office accepted the Kamehameha stamps as prepayment of the 5c Hawaiian postage, 2c ship's fee and the 10c U.S. transcontinental rate (1c overpayment), but did not cancel them, which is not unusual. Honolulu marked the letter "U.S. Postage Paid", and the U.S. stamp was affixed either in Honolulu or San Francisco. It was cancelled in San Francisco 20 days later.
