On June 25, 1942, new overprinted notes were first issued. Series 1935A $1 silver certificate, Series 1934 $5 and $20 Federal Reserve Notes, and Series 1934A $5, $10, and $20 Federal Reserve Notes from the Federal Reserve Bank of San Francisco were issued with brown treasury seals and serial numbers. Overprints of the word HAWAII were made; two small overprints to the sides of the obverse of the note between the border and both the treasury seal and Federal Reserve Bank of San Francisco seal, and large outlined HAWAII lettering dominating the reverse. The purpose was that should there have been an Imperial Japanese invasion of the islands, the US government could immediately declare any Hawaii-printed notes worthless, due to their easy identification.[1][3][5]
With this issue, military officials prohibited the use of non-overprinted notes and ordered all Hawaii residents to turn in regular notes for Hawaii-overprinted notes by July 15, 1942.[4][5] Beginning on August 15, 1942, no other paper U.S. currency could be used except under special permission.[1]
The notes and issuance continued in use until October 21, 1944;[1][3][4][5] by April 1946, notes were being recalled, but many were not destroyed and are still legal tender at their face value, though their numismatic value is considerably higher.[4] Many notes were saved as curios and souvenirs by servicemen.
Destruction of recalled notes
Faced with a $200 million stockpile of US currency, military officials opted to destroy all the recalled regular currency instead of overcoming the logistical problems of shipping the notes back to the mainland.[3][4][5] At first, a local crematorium[a] was pressed into service to burn the notes. To ensure complete destruction, a fine mesh was placed on the top of the chimneys to catch and recirculate unburnt scraps of currency escaping the fire.[3]
Destruction of the notes was slow, and pressed with time, the bigger furnaces of the Aieasugar mill were requisitioned to help burn the currency.[3][4][5]
As a collectible
Of the series, the $5 note is considered the most desirable, as a little over 9 million examples were printed. Over 35 million $1 notes were made, making them the most common of the series. Star notes exist for all the notes, and command a sizable premium.
