AN OUTSTANDING AND RARE MIXED FRANKING FOR THE TWO TREATY RATES IN EFFECT BETWEEN THE UNITED STATES, HAWAII AND GREAT BRITAIN
The July 1, 1870 treaty rate required a 6c stamp, which was not issued in Honolulu until February 14, 1871. For nearly eight months this circumstance resulted in frequent use of the 2c Kamehameha IV in strips of three, but when this practice threatened to deplete the supply of 2c stamps, letter writers resorted to the use of 2c halves with the 5c value - the only period when bisects of Hawaiian stamps were regularly permitted (other than as favors). The new 6c stamps had only been available for 16 days when this cover was mailed - the latest recorded use of this very rare franking
AN ENORMOUSLY RARE AND ATTRACTIVE MIXED-COUNTRY AND MIXED-ISSUE FRANKING
This was franked to pay the 10c Hawaiian Steam Service rate to the U.S., and the 12c rate to Great Britain; however, by the time the cover reached San Francisco, the latter rate had been reduced to 6c.
