Did you find that in circulation??? Very cool, printed for US Solders in Hawaii in WWII. Most were destroyed by the government after they were unneeded. That is considered WWII memorabilia.
I remember reading that the regular currency was loaded on cruise ships and shipped back to the mainland.
The overprint was used so that if the Japanese invaded Hawaii the US could demonetize the currency and not aid the enemy. Same thing with North Africa (but the Nazis of course) with the yellow seal bills.
Those notes were printed just weeks after the United States turned back the Japanese at Midway, 4-7 JUNE 1942. My dad has 1/2 of one and his buddy has the other 1/2. You must understand that territory at that time was under martial law. All civil liberties were suspended. No habeas corpus, no impartial tribunal, all were military judges. Prostitution, gambling, boozing, you name it. Anything the military wanted, they got it.
This is why they say buy the book before the item. All of the different legal notes are featured in just about every price book. These are listed there as well. If you can't afford the book, try the library. If your interested enough to collect, knowing what is out there is your first essential.
According to Peter Huntoon's article from the May-June 2008 edition of Paper Money from the SPMC the regular currency collected in Hawaii was destroyed by burning in Hawaii.
